Astronomers have caught a giant elliptical galaxy “shimmering” as its stars pulsate.
The Fermi Gamma-ray Space Telescope has discovered that almost all of the highest energy photons in the Large Magellanic Cloud come from two pulsars.
NASA’s Mars orbiter MAVEN has painted a detailed picture of how the solar wind robs the Red Planet of its atmosphere.
X-ray observations suggest that flares happen when a black hole's "atmosphere" contracts and launches away from it.
Hubble observations confirm that much of the light that broke up the early universe’s hydrogen came from the smallest galaxies.
On October 28th, the Cassini spacecraft took its deepest dive through the water plume spewing from the south pole of Saturn’s moon Enceladus. It passed only 30 miles (50 kilometers) above the icy surface.
Astronomers have detected debris around a white dwarf that might be from one or more disintegrating rocky planets.
The last hurrah of a star wrenched apart by a supermassive black hole tells astronomers what the stellar crumbs are doing.
Comet 67P’s nucleus was born when two became one.
New maps from NASA’s Dawn spacecraft reveal more about both the landscape and composition of the largest asteroid.
Scientists have confirmed that water-soaked salts likely create dark seasonal lines on Mars.
Astronomers think a bright X-ray source in the galaxy NGC 1313 is a mid-size black hole.
Astronomers have confirmed that the quasar PG 1302-102 is probably a binary supermassive black hole, its members less than a tenth of a light-year apart.
Astronomers have detected waves working together in the solar atmosphere, potentially heating the gas through turbulence.

Astronomers have discovered that one galaxy of a nearby double-galaxy system has a giant, star-studded ring.
Astronomers have identified the smallest supermassive black hole ever detected in a galaxy’s center.
Astronomers have found that a massive filament of gas in the early universe actually seems to be a humongous, galaxy-forming disk.
Astronomers have confirmed the existence of an exoplanet found via microlensing — the first time they’ve been able to successfully follow up on this method.
Astronomers have detected what looks like auroral emission on an ultra-cool star.

NASA’s New Horizons spacecraft whizzed by Pluto this morning just before 8 a.m. EDT at nearly 14 km/s (31,000 mph), about 12,500 km (7,750 miles) above the surface.
The spacecraft orbiting Comet 67P/Churyumov-Gerasimenko has found 18 holes in the nucleus's surface.
New ALMA observations reveal low levels of dust in nine early galaxies, suggesting astronomers should revise some of their calculations.
Scientists have detected glass in Martian craters, created by the fierce heat of impacts that melted the Red Planet’s surface.
