Meet the stars: Pollux, one of the Twins in the sky, is a star that has swelled into its red giant phase while holding onto its Jupiter-like exoplanet, dubbed Thestias.
Scientists Successfully Predicted the Shape of the Solar Corona
Scientists predicted the shape of the solar corona as it would be seen during the August 21, 2017, total solar eclipse. Observations confirmed that they got the broad strokes right.
Tour September's Sky: Goodbye, Venus!
As told in this month's astronomy podcast, Venus is disappearing in the west after sunset. So September offers you a final chance to see four bright planets at once.

Direct Evidence of Water Ice at Moon's Poles
After more than a decade of tantalizing but inconclusive hints, new research shows convincingly that patches of water ice lie exposed on the floors of many permanently shadowed lunar craters.
Rover Call Home: NASA Listens for Opportunity's Wake-up
The Opportunity rover fell silent in June after nearly 15 years of work on the Red Planet. Now the dust storm that prevented its batteries from charging is clearing.
60-second Astro News: Three Stunning Astronomy Pictures
In astronomy news this week: A stunning just-released photo of last year's eclipse, 15,000 galaxies revealed in Hubble's new ultraviolet view of the deep sky, and watching star formation in action in the spiral galaxy M74.
Iron and Titanium Found in Ultrahot Jupiter
New observations provide solid evidence of heavy metals in a gas giant exoplanet’s atmosphere.
Planet Formation Caught in the Act
A team of scientists has captured evidence that PDS 70b, the first directly imaged instance of early planet formation, is actively accreting material, and they’ve measured the rate at which it’s growing.
Auroras Discovered Around Rogue Brown Dwarf
Astronomers have discovered auroras around a set of brown dwarfs — including one that wanders the galaxy by itself — indicating surprisingly strong magnetic fields in these failed stars.
The Storm Begins: Canadian Telescope Spots Its First Radio Burst
The first "fast radio burst" detected by the Canadian CHIME radio telescope is a tantalizing hint of what’s to come.
NASA's Parker Solar Probe Launches to "Touch the Sun"
The unique Parker Solar Probe launched on Sunday, August 12th, set to fly faster and come closer to the Sun than any spacecraft before it.
Sibling Rivalry Caused Eta Carinae's Historic Explosion
Faint echoes of light illuminate what really happened during the Great Eruption of the super-star Eta Carinae.
R Coronae Borealis Awakes and Pluto Blocks a Star
Sometimes, it's just as exciting to watch a celestial object fade or disappear as it is to see it explode. We celebrate the "return" of a mysterious variable star and prepare for Pluto to occult a star.
Catch the Perseid Meteor Shower at Its Peak
Plan for optimal conditions for the year’s Perseid meteor shower, early in the mornings of August 12th and 13th.
Mind the Gap: Gaia Mission Reveals the Insides of Stars
