Kapteyn b: Exoplanet or Illusion?

Recent research casts doubt on whether nearby Kapteyn b, a supposed super-Earth circling in its star’s habitable zone, is a planet at all.


Volcanoes on a Super-Earth?

Observations of nearby super-Earth 55 Cancri e reveal huge, as-yet unexplained changes in the exoplanet’s infrared emission, and volcanoes are one possible cause.


Black Holes

Potential Mid-size Black Hole Found

Scientists have found what seems to be an intermediate-mass black hole in a spiral galaxy 100 million light-years away. If its size is confirmed, it could provide much-needed insight into black hole evolution.

Rosetta Update: Philae Landed in a Hole

The exact location of Philae’s landing site remains unknown, though the site’s topography might allow the lander to operate longer than planned. Meanwhile, Rosetta is detecting organics and heavy elements even when Comet Churyumov-Gerasimenko is far from the Sun.

Opportunity Rover Gets a Cleaning

The Mars rover Opportunity has been cleaned of heavy dust coating its solar panels, thanks to some strong winds blowing over the rim of Endeavour Crater.


Solar System

An Asteroid to Rule Them All

Scientists have new insight into the damage caused by a Rhode Island–size asteroid that hit Earth more than 3 billion years ago, making the rock that wiped out the dinosaurs look like a lightweight.

LADEE Skims the Moon Before Crash

NASA has a fully functioning spacecraft orbiting the Moon, all science goals completed, and a lunar eclipse coming up. It's a perfect opportunity to make some risky but potentially rewarding swoops within 2 miles of the lunar surface.

Brightest Mars in Six Years

Mars is making its nearest and brightest appearance in the night sky since the end of 2007.


Solar System

Rosetta Spots Its Comet

The European Space Agency’s comet-chasing spacecraft has imaged its destination for the first time since waking up from 957 days of hibernation.



Dust in the Heart of Circinus

Infrared observations of the Circinus Galaxy may help reveal the shape of the dusty region fueling its active galactic nucleus and shed light on what governs dust structures in other galaxies.


Solar System

Interactive Mosaic of Moon's North Pole

With the first interactive lunar north pole mosaic released by the NASA’s Lunar Reconnaissance Orbiter Camera team you can explore an area of the Moon’s northern hemisphere about the size of Alaska and Texas combined.



Hubble Displays Galactic Jellyfish

These stunning new images of spiral galaxy ESO 137-001 highlight its violent encounter with the intracluster plasma of Abell 3627, which is stripping away its gas and forming stars in the streamers.

Rocky Encounter with Stellar Lighthouse

Asteroid debris might be bombarding a radio pulsar in the constellation Puppis.


Red Sky for Brown Dwarf

Astronomers have discovered a new “failed star” with unusually red, dusty skies. The dust makes the object look much younger than it actually is, complicating studies of this type of brown dwarf.
