The Andromeda Galaxy Quenches Its Satellite Galaxies Long Before They Fall In November 18, 2025
Galaxies grow massive through mergers with other galaxies. Massive galaxies like the Milky Way and Andromeda not only merge with other large galaxies, they also absorb their much smaller satellite dwarf galaxies. But these smaller galaxies can become quenched long before they're absorbed, and new research examines this process at Andromeda (M31).
How Three Runaway Stars Solved A Galactic Mystery November 18, 2025
All motion is relative. That simple fact makes tracking the motion of distant objects outside our galaxy particularly challenging. For example, there has been a debate among astronomers for decades about the path that one of our nearest neighbors, the Large Magellanic Cloud (LMC), took over the last few billion years. A new paper from […]
How Dark Energy Changed Cosmology Forever November 17, 2025
Let’s rewind the clock back…oh, I don’t know, let’s say a hundred years.
Capturing A Supernova Explosion Only Hours After It Began November 17, 2025
Observations of a supernova explosion have revealed its shape only one day after it was first detected. The exact nature of supernovae explosions are unclear and the subject of ongoing, detailed debate. These new observations with the European Southern Observatory's Very Large Telescope will advance the debate.
Searching For Exoplanets In The Remnants Of A Dwarf Galaxy November 17, 2025
Astronomers have found more than 6,000 exoplanets in the Milky Way. They've even begun to characterize the atmospheres of some of them. But the Milky Way has consumed many of its dwarf satellites. How have exoplanets fared in these remnants? How are they different? To answer those questions, astronomers have to find some of these […]
