Cha J11070768-7626326 (Cha 1107-7626 for short), a young, isolated exoplanet between 5 and 10 times the mass of Jupiter, has experienced a record-breaking...
A supermassive black hole in the center of the radio quasar RACS J032021.44-352104.1 (RACS J0320-35 for short) is growing at one of the fastest rates ever...
Named LID-568, this 7.2-million-solar-mass black hole appears to be feeding on matter at a rate 40 times its Eddington limit and is seen as it existed...
Dynamically active planetary systems orbit a significant fraction of white dwarf stars. These stars often exhibit surface metals accreted from debris disks....
The black hole in the newly-discovered quasar SMSS J052915.80-435152.0 (hereafter called J0529-4351) accretes around one solar mass per day onto an existing...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected a small and vigorous black hole in GN-z11, an exceptionally luminous galaxy...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected a rotating gaseous structure around an extragalactic massive young...
Many planetary scientists studying Jupiter’s moon Europa assumed that it formed with a metallic core during or shortly after accretion. New research...
The newly-discovered black hole resides in the hyperluminous galaxy GN-z11 at a redshift of 11 and could have originated from a stellar mass seed at redshifts...
The detection of the Type Ia supernova SN 2020eyj at radio wavelengths show that the exploded white dwarf had a helium-rich companion.
An artist’s rendition...
AT2021lwx occurred nearly 8 billion years ago and was more than 10 times brighter than any known supernova explosion. The event was likely caused by the...
Astronomers using NASA’s Chandra X-ray Observatory have detected five X-ray events from G29-38, which is among the 100 closest white dwarfs. Their results...
In 2019, the Event Horizon Telescope (EHT) delivered the first resolved images of M87*, the supermassive black hole in the center of the giant elliptical...
New observations of a high-mass protostar in the massive star-forming region G358.93-0.03 shed light on how these young stellar objects accumulate their...
Amir Siraj and Professor Avi Loeb from the Department of Astronomy at Harvard University have developed a new method to search for primordial black holes...
