Can we detect alien civilizations from their space junk?
Looking for satellites orbiting exoplanets may allow us to find civilizations with technology similar to our own. And doing so could be possible with our current observational capabilities.
Deep Spectra with PEPSI
The new high-resolution, hydra-headed PEPSI spectrograph is now in operation. One of the first targets it investigated is an ancient, planet-hosting star.
Where’s the flux? Dust? Discuss.
Tabetha Boyajian calls it “the most mysterious star in the universe.” Has she figured it out?
A Survey of Stellar Activity
Is it an exoplanet… or is it stellar activity in disguise? In today’s astrobite, we explore the stellar activity for a survey of M-Dwarfs, to help us distinguish signals of M-Dwarf stellar activity from the signals of the exoplanets that may be orbiting them.
All spun up
A variety of mechanisms cause stars to experience spin evolution. Can we learn about planet formation by pushing spin measurements down to substellar masses?
Rogue One: The First Einstein Ring Measurements of A Free-Floating Planet
An OGLE microlensing event allowed researchers to find and measure the propeties of a rogue planet.
