Speed check on the ‘fastest’ star in Gaia
Some stars go so fast, they can escape the Milky Way. Today’s article takes a closer look at one of these stars found by Gaia, but is everything as it seems?
Thats no exomoon… or is it? A careful evaluation of evidence for Kepler-1625b-i
Moons of exoplanets have not yet been conclusively. Today’s authors carefully re-evaluate some of the evidence for their own candidate detection of the first known exomoon.
It’s Getting Hot, Hot, Hot With Coronal Loops
Are sunspots the key to answering the decades-old solar coronal heating problem? The authors of today’s paper observe a few sunspot groups to find out.
A Protoplanetary Disk with a Tail
The sites of planet formation seem to be anything but orderly and a recent discovery may help explain the observed wide variety of exoplanet configurations.
Looks like the Sun, but does it spin like the Sun: measuring differential rotation in 16 Cyg A & B
The Sun is known to rotate differentially, which plays a large part in our understanding of solar physics. Do we see the same differential rotation in Solar analogues, 16 Cyg A & B?
A New Window into Prebiotic Nitrogen Chemistry in Protoplanetary Disks
A new survey of complex nitrogen-bearing molecules in nearby protoplanetary disks reveals a surprisingly robust chemistry.
