NASA Citizen Scientists Find New Eclipsing Binary Stars

When two stars orbit one another in such a way that one blocks the other’s light each time it swings around, that’s an eclipsing binary. A new paper from NASA’s Eclipsing Binary Patrol citizen science project presents more than 10,000 of these rare pairs – 10,001 to be precise. These objects will help future researchers study […]

Discovery Alert: A Possible Perpendicular Planet

The Discovery A newly discovered planetary system, informally known as 2M1510, is among the strangest ever found. An apparent planet traces out an orbit that carries it far over the poles of two brown dwarfs. This pair of mysterious objects – too massive to be planets, not massive enough to be stars – also orbit […]

Webb Watches Carbon-Rich Dust Shells Form, Expand in Star System

Astronomers have long tried to track down how elements like carbon, which is essential for life, become widely distributed across the universe. Now, NASA’s James Webb Space Telescope has examined one ongoing source of carbon-rich dust in our own Milky Way galaxy in greater detail: Wolf-Rayet 140, a system of two massive stars that follow […]

Discovery Alert: Mini-Neptune in Double Star System is a Planetary Puzzle

The Discovery A planet that could resemble a smaller version of our own Neptune orbits one of two Sun-like stars that also orbit each other. The planet dwells in the “habitable zone,” with a potentially moderate temperature, and poses a challenge to prevailing ideas of planet formation. Key Facts Astronomers once imagined that our solar […]

NASA’s Fermi Mission Nets 300 Gamma-Ray Pulsars … and Counting

A new catalog produced by a French-led international team of astronomers shows that NASA’s Fermi Gamma-ray Space Telescope has discovered 294 gamma-ray-emitting pulsars, while another 34 suspects await confirmation. This is 27 times the number known before the mission launched in 2008.
