Astronomers have spotted a nearby 'Superearth'

An international team of researchers has discovered a body in space which has been described as a "'superearth' type planet."

A news release issued by an astrophysical institute in the Canary Islands reveals that the planet, named GJ 536 b, has a mass of around 5.4 times that of Earth.

This measure qualifies it as a superearth since the designation refers to a planet whose mass is equal to or greater than Earth's but is also not extraordinarily massive.

Some have speculated that these bodies could be suitable for geologic activity or even potential habitability.

However, the team acknowledges that the planet they discovered does not orbit within its star's habitable zone where liquid water is likely to exist and support life.

But they do believe that its relatively brief 8.7-day-long orbit and its star's luminosity and proximity to our sun could help to provide insight into its atmospheric composition.

The astronomers plan to continue exploring the area around the star because, as one researcher has stated, "Rocky planets are usually found in groups."

A few rare satellites launched by humanity enjoy a full view of Earth from thousands or even a million miles away.

NASA and NOAA created this composite image using photos taken by Suomi NPP, a weather satellite that orbits Earth 14 times a day. You can see the Joalane tropical cyclone in the Indian Ocean (top right).

But it's when we venture deeper into space that Earth comes into spellbinding focus.

Date: November 12, 2009

To rendezvous with comet 67P/Churyumov-Gerasimenko in 2007 — which it will crash into (on September 30, 2016) — the Rosetta spacecraft needed a speed boost with the help of Earth's gravity. This photo it took of Earth shows the South Pole and Antarctica illuminated by the sun.

Date: December 7, 1972

The crew of the last crewed lunar mission, Apollo 17, took this "blue marble" photo of Earth — one of the most-reproduced images in history (though no one is certain which astronaut took it) — from 28,000 miles away on their trip to the moon. Africa is visible at the top left of the image, and Antarctica on the bottom.

And it drifts utterly alone in the blackness of space.

The moon — a cold, airless ball of rock 50 times smaller than Earth — is our largest and closest celestial friend.

Taken by: William Anders of Apollo 8's crew

Date: December 24, 1968

NASA's famous "Earthrise" image was taken as Apollo 8 astronauts Frank Borman, Jim Lovell, and William Anders swung around the moon. During a broadcast with Earth, Lovell said: "The vast loneliness is awe-inspiring and it makes you realize just what you have back there on Earth."

Its kinship with us is uncanny: The moon formed after a Mars-size planet smacked into a proto-Earth some 4.5 billion years ago.

Launched by NASA in 2009, LRO normally stares down at the cratered surface of the moon — but took a moment to snap this modern-day "Earthrise" composite photo.

We know this only because, since the 1950s, nations all around the world have launched people and robots there.


Taken by: Lunar Orbiter 1

Date: August 23, 1966

Lunar Orbiter 1 took this photo while scouting for places astronauts might land on the moon. Because 1960s technology couldn't access the full depth of image data that NASA had recorded on analog tapes, however, the Lunar Orbiter Image Recovery Project recently recovered this version of the famous image. The full-size version is large enough to print as a billboard.


Our lunar exploration is a mixed pursuit of technological conquest...

China has grown increasingly capable of exploring the solar system alongside NASA, ESA, Russia, India, and other space-faring nations. Its next moon mission: to return a lunar soil sample in 2017; if it succeeds, it will be the first collected since the last Apollo missions in the 1970s.

The Earth never seems to be too distant from the moon.

Date: 1994

The Clementine mission was launched on January 25, 1994, as part of a joint NASA-strategic defense initiative. Before spinning wildly out of control on May 7, 1994, it took this composite photo of Earth, as seen across the northern pole of the moon.


But the farther out we send our spacecraft...

The more peculiar our home looks...


Taken by: Galileo

Date: December 16, 1992

On its way to study Jupiter and its moons, NASA's Galileo spacecraft got its second speed boost from Earth's gravity. About a week after that maneuver it took this composite image from 3.9 million miles away. The moon, which is about one-third as bright as Earth, is closer to the viewer in the foreground.

And the more lonely it seems.

Taken by: Near Earth Asteroid Rendezvous (NEAR)

Date: January 23, 1998

NASA's asteroid-bound NEAR spacecraft took this two-part image of Earth and the moon from about 250,000 miles. Antarctica is visible in the south pole. NEAR eventually reached Asteroid 433 Eros, began orbiting the space rock, and deployed its Shoemaker lander spacecraft in 2001.


Most images don't accurately portray the distance between Earth and the moon. 

Taken by: Voyager 1

Date: September 18, 1977

Most photos of Earth and the moon are (artful) cut-and-paste composites, since they are so far away from one another. However, this is the first photo of both worlds ever taken in a single frame, when Voyager 1 was 7.25 million miles away — en route to its "grand tour" of the solar system.

Only by traveling hundreds of thousands or millions of miles away, then turning around, can we truly appreciate what the 239,000 miles between two worlds actually looks like.


Taken by: Mars Express

Date: July 3, 2003

Nearly 5 million miles from Earth and on its way to the Red Planet, the Mars Express spacecraft pointed back home and snapped this photo. The satellite has orbited Mars and photographed its surface in 3D since December 2003.
