Tracking Gas in Star-Forming Galaxies
How has galaxy evolution changed over our universe’s history? New observations of evasive gas provide clues.
Possibly Impossible Planets
To constrain models of planetary formation, we need to know what sorts of planets can form. So which ones do?
Should We Blame Pulsars for Too Much Antimatter?
A new study explores whether two nearby pulsars are causing the surplus of high-energy positrons we measure at Earth.
Watching Stars Evolve in Real Time
A collection of more than 100 years of data has now given us a rare opportunity to watch, in real time, as a star evolves.
When Black Holes Shred Sun-Like Stars
When a passing star gets a little too close to a massive black hole, destruction ensues. But how does the star’s age affect the outcome?
Two Eyes to Hunt Stray Planet Masses
How can we measure the masses of free-floating planets? One way is to combine the power of two upcoming missions.
Uniting Short Gamma-ray Bursts and Neutron Star Mergers
Are short gamma-ray bursts — brief flashes of high-energy emission — created by the collision of two neutron stars?
Are There More Stars Like Boyajian’s Star?
We thought that the bizarre dimming events of Boyajian’s star made it a one-of-a-kind source. But what if it isn’t?
