Approximately every two Earth years, when it is summer on the southern hemisphere of Mars, a window opens: Only there and only in this season can water vapor efficiently rise from the lower into the upper atmosphere. There, winds carry the rare gas to the North Pole. While part of the water vapor decays and ...
On April 10, 2019, images of the first black hole in human history were revealed, which is the symbolic achievement of a new milestone in human science. Taiwan’s role in black hole image It is understood that the first black hole image was very difficult to come by. Eight enormous radio telescopes, networked together to ...
Astronomers have discovered rapidly swinging jets coming from a black hole almost 8,000 light-years from Earth. Published today in the journal Nature, the research shows jets from V404 Cygni’s black hole behaving in a way never seen before on such short timescales. The jets appear to be rapidly rotating with high-speed clouds of plasma — ...
As fascinating as it is mysterious, dark matter is one of the greatest enigmas of astrophysics and cosmology. It is thought to account for 90 percent of the matter in the Universe, but its existence has been demonstrated only indirectly and recently called into question. New research conducted by SISSA removes the recent doubts on the ...
Observers watching January’s total eclipse of the Moon saw a rare event, a short-lived flash as a meteorite hit the lunar surface. Spanish astronomers now think the space rock collided with the Moon at 61,000 km/h, excavating a crater 10 to 15 meters across. Prof. Jose Maria Madiedo of the University of Huelva, and Dr. ...
It has only been within the past few centuries that Western scientists started proposing there might be water on Mars. In 1784, German astronomer William Herschel even put forward the idea that there might be inhabitants on the planet similar to us. Though the idea of Martian humanoids remains in the realm of science fiction, ...
Ever since the idea of a wormhole was first introduced, scientists and the public alike have always wondered whether traveling through them would be possible. Since wormholes connect two points in space, they were theorized to be a speedy way to traverse galaxies. But Daniel Jafferis, a physicist from Harvard University says that even though ...
NASA has discovered that the Moon ejects water vapor into the atmosphere every time a meteoroid strikes its surface. The discovery, made by researchers from the space agency and the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, is expected to help scientists understand the history of lunar water. Water on the Moon Even ...
For five months in mid-2017, Emily Mason did the same thing every day. Arriving at her office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, she sat at her desk, opened up her computer, and stared at images of the Sun — all day, every day. “I probably looked through three or five years’ ...
After drawing both praise and skepticism, the team of astronomers who discovered NGC 1052-DF2 — the very first known galaxy to contain little to no dark matter — is back with stronger evidence about its bizarre nature. Dark matter is a mysterious, invisible substance that typically dominates the makeup of galaxies; finding an object missing ...
