Astronomers from Japan, Taiwan and U.S. have discovered 83 quasars powered by supermassive black holes in the distant universe, from a time when the universe was only 5 percent of its age.
Using ESA's Gaia spacecraft and NASA’s Hubble Space Telescope, astronomers have come up with the most accurate measurement yet of the Milky Way’s total mass. It contains about 1.5 trillion times the mass of Earth’s Sun.
An extreme form of solar storm, known as a solar proton event (SPE) struck our planet in 660 BCE. If an event of such magnitude were to happen today, it would likely wreak havoc on our technological infrastructure.
Located in the constellation of Hercules, about 230 million light-years away, NGC 6052 is a pair of colliding galaxies. This particular image was taken using the Wide Field Camera 3 on the NASA/ESA Hubble Space Telescope.
Indeed, the Demo-1 mission went exactly as planned, signifying an important milestone for the U.S. as it strives to regain its ability to independently send astronauts into space.
A research into how life evolved on Earth has shown that water alone does not guarantee life – nor does the presence of oxygen gas. And that two other major biosignatures, carbon dioxide and carbon monoxide could be needed.
Recent U.S. study suggests how surveys using gamma telescopes could find evidence of spacecraft powered by tiny artificial black holes. The concept of a black hole-powered spacecraft was first introduced by science fiction author Arthur C. Clarke.
The “quiet” black hole is located just 20 light years from the supermassive four-million-solar-mass black hole lurking at the centre of the Milky Way. In the future, it will fall into the supermassive black hole.
Juno took the photo 8,000 miles from the cloud tops during its 18th close flyby of Jupiter on February 12. Overall, 32 flybys are planned, so Juno is just beginning the second half of its flybys.
NASA and SpaceX announced that they are ready to conduct the first orbital launch of Crew Dragon as early as March 2nd, a demonstration that will directly precede the first crewed launch on a US rocket in more eight years.
Virgin Galactic has reached another milestone in their fight test program. The flight took place on February 22nd and three people in the crew spent several weightless minutes aboard the spacecraft.
There’s a massive, growing wall of evidence showing that Mars may have had the necessary conditions for life in the past. ESA’s High-Resolution Camera on the Mars Express Orbiter, there are clear signs of a system of river valleys.
Neptune has a new moon, and it’s also the gas giant’s smallest to date — only a little over 20 miles across. It was discovered using the Hubble Space Telescope combined with a new method to track dim objects as they orbit.
On Thursday, SpaceIL's spacecraft, Beresheet, was launched aboard a SpaceX rocket. It will take a couple of months for it to reach the moon, and landing will be the most difficult part.
A release of data gathered by the Low Frequency Array (LOFAR) telescope network in Europe has discovered more than 300,000 potential galaxies in a tiny corner of the northern sky.
