How a Black Hole Collision Could Explain the Milky Way’s S-Stars
What’s responsible for the haphazard orbits of the stars closest to our galaxy’s supermassive black hole? A second black hole, perhaps.
Astronomers Spot Possible Disk in Rubin Observatory First-Look Image
One of the first-look images from the Vera C. Rubin Observatory contained a rare find: a candidate circumstellar or protoplanetary disk in a region where few such disks have been discovered.
A Candidate Direct-Collapse Black Hole in the Infinity Galaxy
A search for oddities in archival JWST data has turned up something remarkable: a rare pair of collisional ring galaxies that may have birthed a supermassive black hole during their clash.
Double Disruption Dilemma: Exploring the Tidal Disruption Events of AT 2022dbl
A recently discovered tidal disruption event has astronomers investigating new ways in which stars may be ripped apart by supermassive black holes.
Minding the Gaps in Solar Wind Data
A new method for handling data with significant gaps can be applied to extremely sparse datasets, such as Voyager data from the outer heliosphere.
Exo-Saturns and Exo-Jupiters Are Within JWST’s Reach
New research suggests that JWST is capable of directly imaging planets that resemble the gas giants in our solar system, provided they orbit nearby stars.
Citizen Science Born in the Pandemic: The Hubble Image Similarity Project
A team of citizen scientists compared 5.4 million pairs of astronomical images, helping researchers create a database of image similarity information that can be used to test image-search algorithms.
Finding Galaxies in the Dark: Using Globular Clusters to Identify Ultra-Diffuse Galaxies
With their extremely low surface brightness, ultra-diffuse galaxies are very difficult to detect, but a recent study has spotted one by searching for its globular clusters.
Monthly Roundup: The Supermassive Black Hole of Messier 87
The massive nearby elliptical galaxy Messier 87 hosts one of the most-studied supermassive black holes in the universe. What have researchers recently learned about this black hole’s spin, jets, and flares?
