A ghost is haunting our universe. This has been known in astronomy and cosmology for decades. Observations suggest that about 85% of all the matter in the universe is mysterious and invisible. These two qualities are reflected ...
Well over 5,000 planets have been found orbiting other star systems. One of the satellites hunting for them is TESS, the Transiting Exoplanet Survey Satellite. Astronomers using TESS think they are made a rather surprising ...
European astronomers have investigated a recently detected black hole designated Gaia BH3. In their results, they found that the black hole is associated with a nearby disrupted star cluster known as ED-2. The finding is ...
New movies of two of the most famous objects in the sky—the Crab Nebula and Cassiopeia A—are being released from NASA's Chandra X-ray Observatory. Each includes X-ray data collected by Chandra over about two decades. ...
While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays—high-energy photons—coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for ...
An international study, led by researchers from Monash University, has revealed crucial insights into black hole dynamics within massive disks at the centers of galaxies.
The universe's early galaxies were less chaotic and developed much faster than previously thought, according to new research looking back more than ten billion years in time. An international team of astronomers led by Durham ...
In celebration of the 34th anniversary of the launch of NASA's legendary Hubble Space Telescope on April 24, astronomers took a snapshot of the Little Dumbbell Nebula (also known as Messier 76, M76, or NGC 650/651) located ...
South Africa's Karoo region is a vast semi-arid area that stretches across four of the country's provinces. It is sparsely populated and renowned for its wide open spaces.
Thanks to new sophisticated techniques and state-of-the-art facilities, astronomy has entered a new era in which the depth of the sky can finally be accessed. The ingredients of our cosmic home, the Milky Way galaxy—stars, ...
