The James Webb Space Telescope may have found dozens of elusive brown dwarfs — strange objects larger than planets but smaller than stars — beyond the Milky Way for the first time ever.
At the High-Altitude Water Cherenkov (HAWC) observatory, positioned 13,000 feet above sea level on Mexico's Sierra Negra volcano, scientists have uncovered unprecedented levels of gamma-ray energy from the center of the Milky Way. This…
Remember that amazing “first image” of Sagittarius A* (Sgr A) black hole at the heart of the Milky Way? Well, it may not be completely accurate, according to researchers at the National Astronomical Observatory of Japan (NAOJ). Instead,…
A research team led by Assistant Professor Makoto Miyoshi of the National Astronomical Observatory of Japan (NAOJ) has independently re-analyzed observation data of the supermassive black hole at the center of the Milky Way galaxy obtained…
At the High-Altitude Water Cherenkov (HAWC) observatory, situated 13,000 feet above sea level on Mexico's Sierra Negra volcano, researchers have made a remarkable discovery concerning the Milky Way galaxy. An international research team,…
This stunning image of a star cluster in the Small Magellanic Cloud (SMC) is more than just a pretty picture. It’s part of a scientific effort to understand star formation in an environment different from ours. The young star cluster is…
Near the outskirts of the Small Magellanic Cloud, a satellite galaxy roughly 200,000 light-years from Earth, lies the young star cluster NGC 602. The local environment of this cluster is a close analog of what existed in the early universe…
Astronomers have detected ultra-high-energy gamma rays coming from the center of the Milky Way, with nearly 100 events of more than 100 teraelectron volts of energy. Researchers aren't sure what's generating so many of these extreme events…
At the High-Altitude Water Cherenkov (HAWC) observatory, 13,000 feet above sea level on the Sierra Negra volcano of Mexico, researchers are getting a look into a violent mystery in the Milky Way galaxy. An international research team co…
Over the last week, we’ve been entertained by a pre-Halloween visitor from the depths of our solar system. It’s Comet Tsuchinshan-Atlas, a ghostly dirty snowball of rock, gas, and dust partially melting before our very eyes. The solid 2 to…
