The best places to watch tonight's stunning meteor shower

Make a Wish: The Geminid Meteor Shower Peaks Sunday Night

A dazzling meteor shower is happening tonight with perfect viewing conditions.

Each December, we're treated to the Geminid meteor shower, but this year's will be a great time to check out the show -- even for people in the city.

That's because the moon will be just a couple of days past its new moon phase, which means there will be hardly any moonlight to outshine the meteors as they race across the sky.

The Geminid meteor shower takes place throughout December, but the best time to watch -- when astronomers estimate you can see as many as 100 meteors an hour — will be around 2 am early Monday morning on Dec. 14.

New Horizons scientists made this false color image of Pluto using a technique called principal component analysis to highlight the many subtle color differences between Pluto's distinct regions. The image data were collected by the spacecraft’s Ralph/MVIC color camera on July 14 at 11:11 AM UTC, from a range of 22,000 miles (35,000 kilometers). This image was presented by Will Grundy of the New Horizons’ surface composition team on Nov. 9 at the Division for Planetary Sciences (DPS) meeting of the American Astronomical Society (AAS) in National Harbor, Maryland.

Scientists often use the combined power of multiple telescopes to reveal the secrets of the Universe – and this image is a prime example of when this technique is strikingly effective.

The yellow-hued object at the centre of the frame is an elliptical galaxy known as Hercules A, seen by the Earth-orbiting NASA/ESA Hubble Space Telescope. In normal light, an observer would only seethis objectfloating in the inky blackness of space.

However, view Hercules A with a radio telescope, and the entire region is completely transformed. Stunning red–pink jets of material can be seen billowing outwards from the galaxy – jets that are completely invisible in visible light. They are shown here as seen by theKarl G. Jansky Very Large Arrayradio observatory in New Mexico, USA. These radio observations were combined with the Hubble visible-light data obtained with the Wide Field Camera 3 to create this striking composite. (Photo via NASA, ESA, S. Baum & C. O’Dea (RIT), R.

The latest results from the “Cheshire Cat” group of galaxies show how manifestations of Einstein’s 100-year-old theory can lead to new discoveries today. 

One hundred years ago this month, Albert Einstein published his theory of general relativity, one of the most important scientific achievements in the last century.

A key result of Einstein’s theory is that matter warps space-time, and thus a massive object can cause an observable bending of light from a background object.  The first success of the theory was the observation, during a solar eclipse, that light from a distant background star was deflected by the predicted amount as it passed near the sun.

Astronomers have since found many examples of this phenomenon, known as “gravitational lensing.” More than just a cosmic illusion, gravitational lensing provides astronomers with a way of probing extremely distant galaxies and groups of galaxies in ways that would otherwise be impossible even with the most powerful telescopes.

The latest results from the “Cheshire Cat” group of galaxies show how manifestations of Einstein’s 100-year-old theory can lead to new discoveries today. Astronomers have given the group this name because of the smiling cat-like appearance.  Some of the feline features are actually distant galaxies whose light has been stretched and bent by the large amounts of mass, most of which is in the form of dark matter detectable only through its gravitational effect, found in the system.

More specifically, the mass that distorts the faraway galactic light is found surrounding the two giant “eye” galaxies and a “nose” galaxy. The multiple arcs of the circular “face” arise from gravitational lensing of four different background galaxies well behind the “eye” galaxies. The individual galaxies of the system, as well as the gravitationally lensed arcs, are seen in optical light from NASA’s Hubble Space Telescope.

Each “eye” galaxy is the brightest member of its own group of galaxies and these two groups are racing toward one another at over 300,000 miles per hour. Data from NASA’s Chandra X-ray Observatory (purple) show hot gas that has been heated to millions of degrees, which is evidence that the galaxy groups are slamming into one another. Chandra’s X-ray data also reveal that the left “eye” of the Cheshire Cat group contains an actively feeding supermassive black hole at the center of the galaxy.

Astronomers think the Cheshire Cat group will become what is known as a fossil group, defined as a gathering of galaxies that contains one giant elliptical galaxy and other much smaller, fainter ones. Fossil groups may represent a temporary stage that nearly all galaxy groups pass through at some point in their evolution.  Therefore, astronomers are eager to better understand the properties and behavior of these groups.

The Cheshire Cat represents the first opportunity for astronomers to study a fossil group progenitor. Astronomers estimate that the two “eyes” of the cat will merge in about one billion years, leaving one very large galaxy and dozens of much smaller ones in a combined group. At that point it will have become a fossil group and a more appropriate name may be the “Cyclops” group.

On Nov. 6, 2015, NASA astronauts Scott Kelly and Kjell Lindgren spent 7 hours and 48 minutes working outside the International Space Station on the 190th spacewalk in support of station assembly and maintenance. The astronauts restored the port truss (P6) ammonia cooling system to its original configuration, the main task for the spacewalk. They also returned ammonia to the desired levels in both the prime and back-up systems. The spacewalk was the second for both astronauts. Crew members have now spent a total of 1,192 hours and 4 minutes working outside the orbital laboratory.

At about an hour after the 6:22 a.m. EST start of the spacewalk, astronaut Kjell Lindgren took this photograph of Scott Kelly at work, with the station's solar arrays visible in the background. (Photo via NASA)

This stunning image of the northwest corner of Australia was snapped by a student on Earth after remotely controlling the Sally Ride EarthKAMaboard the International Space Station. The EarthKAM program allows students to request photographs of specific Earth features, which are taken by a special camera mounted on the space station when it passes over those features. The images are posted online for the public and students in participating classrooms around the world to view.

EarthKAM is the only program providing students with such direct control of an instrument on a spacecraft orbiting Earth, teaching them about environmental science, geography and space communications.The project was initiated by Dr. Sally Ride, America’s first woman in space, in 1995 and called KidSat; the camera flew on five space shuttle flights before moving to the space station on Expedition 1 in 2001. In 2011, NASA and Sally Ride Science installed a new camera system in a downward-pointing window on the station. This camera system is responsible for taking and downloading student image requests.

In July 2015, researchers announced the discovery of a black hole, shown in the above illustration, that grew much more quickly than its host galaxy. The discovery calls into question previous assumptions on the development of galaxies. The black hole was originally discovered using NASA's Hubble Space Telescope, and was then detected in the Sloan Digital Sky Survey and by ESA's XMM-Newton and NASA's Chandra X-ray Observatory. (Illustration via M.

NASA astronaut Kjell Lindgren took this photograph on Nov. 11, 2015 from the International Space Station, and shared it with his followers on social media. Lindgren wrote, "The delicate fingerprints of water imprinted on the sand. The #StoryOfWater." The area photographed is located in Oman, approximately 20 km to the west-northwest of Hamra Al Drooa.

One of the ways research on the space station benefits life on Earth is by supporting water purification efforts worldwide. Drinkable water is vital for human survival. Unfortunately, many people around the world lack access to clean water. Using technology developed for the space station, at-risk areas can gain access to advanced water filtration and purification systems, making a life-saving difference in these communities. Joint collaborations between aid organizations and NASA technology show just how effectively space research can adapt to contribute answers to global problems. The commercialization of this station-related technology has provided aid and disaster relief for communities worldwide. (Photo via NASA)

Astronomers have discovered a giant gathering of galaxies in a very remote part of the universe, thanks to NASA's Spitzer Space Telescope and Wide-field Infrared Survey Explorer (WISE). The galaxy cluster, located 8.5 billion light-years away, is the most massive structure yet found at such great distances.

The galaxy cluster called MOO J1142+1527 can be seen here as it existed when light left it 8.5 billion years ago. The red galaxies at the center of the image make up the heart of the galaxy cluster. (Photo via NASA/JPL-Caltech/Gemini/CARMA)

Ophir Chasma forms the northern portion of Valles Marineris, and this image features a small part of its wall and floor.

The wall rock shows many sedimentary layers and the floor is covered with wind-blown ridges, which are intermediate in size between sand ripples and sand dunes. Rocks protruding on the floor could be volcanic intrusions of once-molten magma that have pushed aside the surrounding sedimentary layers and "froze" in place.

Images like this can help geologists study the formation mechanisms of large tectonic systems like Valles Marineris. (Photo via NASA/JPL-Caltech/Univ. of Arizona)

Only three local stars appear in this image, quartered by right-angled diffraction spikes. Everything besides them is a galaxy; floating like a swarm of microbes in a drop of water, and brought into view here not by a microscope, but by the Advanced Camera for Surveys on the Hubble Space Telescope.

In the foreground, the spiral arms of MCG+01-02-015 seem to wrap around one another, cocooning the galaxy. The scene suggests an abundance of galactic companionship for MCG+01-02-015, but this is a cruel trick of perspective. Instead, MCG+01-02-015’s unsentimental naming befits its position within the cosmos: it is a void galaxy, the loneliest of galaxies.

The vast majority of galaxies are strung out along galaxy filaments — thread-like formations that make up the large-scale structure of the universe — drawn together by the influence of gravity into sinuous threads weaving through space. Between these filaments stretch shallow but immense voids; the universe’s wastelands, where, outside of the extremely rare presence of a galaxy, there is very little matter — about one atom per cubic meter. One such desolate stretch of space is what MCG+01-02-015 reluctantly calls home.

The galaxy is so isolated that if our galaxy, the Milky Way, were to be situated in the same way, we would not even have known of the existence of other galaxies until the development of strong telescopes and detectors in the 1960s.

At the center of this amazing Hubble image is the elliptical galaxy NGC 3610. Surrounding the galaxy are a wealth of other galaxies of all shapes. There are spiral galaxies, galaxies with a bar in their central regions, distorted galaxies and elliptical galaxies, all visible in the background. In fact, almost every bright dot in this image is a galaxy — the few foreground stars are clearly distinguishable due to the diffraction spikes (lines radiating from bright light sources in reflecting telescope images) that overlay their images.

NGC 3610 is of course the most prominent object in this image — and a very interesting one at that! Discovered in 1793 by William Herschel, it was later found that this elliptical galaxy contains a disk. This is very unusual, as disks are one of the main distinguishing features of a spiral galaxy. And the disk in NGC 3610 is remarkably bright.

The reason for the peculiar shape of NGC 3610 stems from its formation history. When galaxies form, they usually resemble our galaxy, the Milky Way, with flat disks and spiral arms where star formation rates are high and which are therefore very bright. An elliptical galaxy is a much more disordered object which results from the merging of two or more disk galaxies. During these violent mergers most of the internal structure of the original galaxies is destroyed. The fact that NGC 3610 still shows some structure in the form of a bright disk implies that it formed only a short time ago. The galaxy’s age has been put at around four billion years and it is an important object for studying the early stages of evolution in elliptical galaxies.

Saturn's frigid moon Titan has some characteristics that are oddly similar to Earth, but still slightly alien. It has clouds, rain and lakes (made of methane and ethane), a solid surface (made of water ice), and vast dune fields (filled with hydrocarbon sands).

The dark, H-shaped area seen here contains two of the dune-filled regions, Fensal (in the north) and Aztlan (to the south).

Cassini's cameras have frequently monitored the surface of Titan (3200 miles or 5150 kilometers across) to look for changes in its features over the course of the mission. Any changes would help scientists better understand different phenomena like winds and dune formation on this strangely earth-like moon.

For a closer view of Fensal-Aztlan, see PIA07732.

This view looks toward the leading side of Titan. North on Titan is up. The image was taken with the Cassini spacecraft narrow-angle camera on July 25, 2015 using a spectral filter sensitive to wavelengths of near-infrared light centered at 938 nanometers.

The view was obtained at a distance of approximately 450,000 miles (730,000 kilometers) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 32 degrees. Image scale is 3 miles (4 kilometers) per pixel.

The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado. (Photo via NASA/JPL-Caltech/Space Science Institute)

This curious galaxy — only known by the seemingly random jumble of letters and numbers 2MASX J16270254+4328340 — has been captured by the NASA/ESA Hubble Space Telescope dancing the crazed dance of a galactic merger. The galaxy has merged with another galaxy leaving a fine mist, made of millions of stars, spewing from it in long trails.

Despite the apparent chaos, this snapshot of the gravitational tango was captured towards the event’s conclusion. This transforming galaxy is heading into old age with its star-forming days coming to an end. The true drama occurred earlier in the process, when the various clouds of gas within the two galaxies were so disturbed by the event that they collapsed, triggering an eruption of star formation. This flurry of activity exhausted the vast majority of the galactic gas, leaving the galaxy sterile and unable to produce new stars.

As the violence continues to subside, the newly formed galaxy’s population of stars will redden with age and eventually begin to cool and dim one by one. With no future generations of stars to take their place, the galaxy thus begins a steady path of fading and quieting.

For the second time in a week, a major cyclone moved toward the Arabian Peninsula and the nation of Yemen. To have a cyclone or hurricane hit any nation twice in a week is not a common occurrence; to have two storms to hit one region of the Middle East is unprecedented. Only three cyclones have made landfall on the Peninsula across six decades of records.

Cyclone Megh has already battered Socotra, an island off the Yemeni coast in the Arabian Sea. The storm passed over the island on Nov. 8, 2015, with estimated wind speeds approaching 125 miles per hour. U.S. Navy forecasters predict that Megh will make landfall near Aden, on the mainland of Yemen, on November 10. The winds are likely to be tropical storm force by then, though the system should drop copious amounts of rain on the desert nation. Rainfall last week led to extensive flooding in central and eastern Yemen.

The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite acquired this view of Cyclone Megh in the narrow Gulf of Aden at 2:05 p.m. local time (10:05 Universal Time) on Nov. 9, 2015. At the time, the cyclone had sustained winds of approximately 75 knots (85 miles or 140 kilometers per hour). (Photo via NASA/Jeff Schmaltz)

Although Dione (near) and Enceladus (far) are composed of nearly the same materials, Enceladus has a considerably higher reflectivity than Dione. As a result, it appears brighter against the dark night sky.

The surface of Enceladus (313 miles or 504 kilometers across) endures a constant rain of ice grains from its south polar jets. As a result, its surface is more like fresh, bright, snow than Dione's (698 miles or 1123 kilometers across) older, weathered surface. As clean, fresh surfaces are left exposed in space, they slowly gather dust and radiation damage and darken in a process known as "space weathering."

This view looks toward the leading hemisphere of Enceladus. North on Enceladus is up and rotated 1 degree to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sept. 8, 2015. (Photo via NASA/JPL-Caltech/Space Science Institute)

This galaxy is known as Mrk 820 and is classified as a lenticular galaxy — type S0 on the Hubble Tuning Fork. The Hubble Tuning Fork is used to classify galaxies according to their morphology. Elliptical galaxies look like smooth blobs in the sky and lie on the handle of the fork. They are arranged along the handle based on how elliptical they are, with the more spherical galaxies furthest from the tines of the fork, and the more egg-shaped ones closest to the end of the handle where it divides. The two prongs of the tuning fork represent types of unbarred and barred spiral galaxies.

Lenticular galaxies like Mrk 820 are in the transition zone between ellipticals and spirals and lie right where the fork divides. A closer look at the appearance of Mrk 820 reveals hints of a spiral structure embedded in a circular halo of stars.

Surrounding Mrk 820 in this image is a good sampling of other galaxy types, covering almost every type found on the Hubble Tuning Fork, both elliptical and spiral. Most of the smears and specks are distant galaxies, but the prominent bright object at the bottom is a foreground star called TYC 4386-787-1. (Photo via ESA/Hubble & NASA and N.

"If you live under the artificial skyglow of light pollution, you'll see fewer meteors, but the brightest ones will shine through," the editors of Sky and Telescope reported.

Those brighter ones that Sky and Telescope is referring to will likely be what experts call fireballs, Mike Hankey, who is the operations manager for the American Meteor Society, told Business Insider. Fireballs are extremely luminous meteors that shine as bright as Venus -- the brightest objects in the night sky next to the moon.

If you want to catch a truly spectacular show tonight, however, your best bet is to get far away from city lights.

"Generally if you can drive 30 minutes or more away from the city, you'll be OK," Hankey told Business Insider last August, referring to that month's Perseid meteor shower. But the 30-minute rule applies for nearly every meteor shower.

City lights tend to drown out most objects in the night sky, and that includes meteors. Here's a map that Hankey provided showing light pollution from city lights across the country:

light pollution us


"If you made it to an orange zone or better, you'd be able to observe," he told us in August. "Another way to gauge the light — if you can see some stars, then you can see some meteors. If you look up and see nothing, then you need to keep moving away from the city."

And if there's no good place for you to observe, then your best bet is to watch the online Slooh observatory's live broadcast of the show starting at 8 pm ET tonight, Sunday, Dec. 13.

During the broadcast, Slooh astronomers Bob Berman and Will Gater will discuss the mysterious origins of the Geminids. You can ask them questions about all things meteor-related by tweeting @slooh on Twitter.
