Scientists had suspected that mountains on Venus affected weather patterns seen rippling across Venus’ cloudtops. A new study provides evidence of this connection.
Watch a full year of Earth’s sunlit side, seen from a million miles away by the DSCOVR spacecraft.
First total solar eclipse visible from the U.S. since 1991 (seen only from part of Hawaii), and first visible from contiguous U.S. since 1979. Start planning now!
Computer models, and observations of our galaxy and others, suggested a Milky Way X, made of stars. An analysis of data from the WISE space telescope reveals it.
Mare Imbrium basin on the moon – the Man in the Moon’s right eye – might have been made by a protoplanet-sized impact, 3.8 billion years ago.

Today is the 47th anniversary of humanity’s historic first steps on the moon. The story in pictures, here.
First distinct (resolved) observation of a water snow line – aka a frost line – the distance from a star where temperatures drop so low that water turns to ice.
New video released on 1-year anniversary of New Horizons’ visit to Pluto. It lets you ride aboard a Pluto spacecraft and then plunge toward its surface!

That’s from 197 new exoplanet candidates. In its extended (K2) mission, the Kepler space telescope has been looking toward cool, small, red dwarf-type stars.
Nature and nurture in the evolution of galaxies, and what those factors mean with respect to whether galaxies continue forming stars, or not.
What are the odds? Peter Lowenstein caught Venus and Mercury on the evening of their conjunction – July 16, 2016 – setting through a thin break in the clouds.
Rosetta and its instruments have been in harsh outer space for 12 years, the last 2 of which have been in the dusty realm of a comet near the sun.
Stellar mergers that cause gamma ray bursts might make pencil-thin jets. If true, since most jets won’t be pointed our way, we’ll see no sign of most mergers.
A new map of the universe – based on observations of 1.2 million galaxies – confirms cosmologists’ theories about the web of galaxies making up our universe as a whole.
In early July, a satellite camera caught the moon crossing the face of Earth.
How NASA is working to keep Earth safe from asteroids and other hazards that come from deep space.
Color view from JunoCam, showing the planet, the Red Spot and several moons. Plus … calling all astrophotographers to participate in the mission!
Peering deeper into the Orion Nebula than ever before, astronomers have found a plethora of low-mass objects, some isolated “planets” and some brown dwarfs.
