Astronomers have observed an exoplanet orbiting a star in just over 18 hours, the shortest orbital period ever observed for a planet of its type. It means that a single year for this hot Jupiter — a gas giant similar in size and composition to Jupiter in our own solar system — passes in less ...
Death is inevitable. All things come to an end, as they say. And what comes from the earth, will always go back to its embrace. But what if, perchance, you were qualified to go on a voyage to one of the closest neighbors in our solar system — Mars? Say you had lived for a ...
In 2017, a Chinese-run space station in Argentina’s Patagonia region was inaugurated. According to officials, the space station is solely used for scientific purposes. However, the fact that its operations are managed by the Chinese military raises strong suspicions about the facility. The space station The station is located on a 494-acre compound and is ...
The Breakthrough Listen Initiative released data from the most comprehensive survey yet of radio emissions from the plane of the Milky Way Galaxy and the region around its central black hole, and it is inviting the public to search the data for signals from intelligent civilizations. At a media briefing in Seattle as part of ...
Using ESO’s Very Large Telescope (VLT), astronomers have captured the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation of Orion. The stunning new images of the star’s surface show not only the fading red supergiant, but also how its apparent shape is changing. Betelgeuse has been a beacon in the night sky ...
A new study led by the University of Hawai‘i (UH) at Mānoa has helped refine our understanding of the amount of hydrogen, helium, and other elements present in violent outbursts from the Sun and other types of solar “wind,” a stream of ionized atoms ejected from the Sun. Coronal mass ejections (CME) are giant plasma bursts that ...
In space, astronauts often live with the risk of being exposed to too much radiation, which could cause severe damage to their long-term health. Researchers have discovered a strain of fungus that might help resolve this issue. This particular fungus, called Cryptococcus neoformans, apparently has the ability to feed on radiation and was discovered at ...
An object 500 million light-years away from Earth has been sending signals once every 16 days, baffling scientists. Such signals, called Fast Radio Bursts (FRB), have been detected before. In fact, scientists already know about 100 types of FRBs. But what makes this specific FRB special is that it is the only one to have ...
An international team of astronomers led by scientists at the University of California, Riverside, has found an unusual monster galaxy that existed about 12 billion years ago when the universe was only 1.8 billion years old. Dubbed XMM-2599, the galaxy formed stars at a high rate and then died. Why it suddenly stopped forming stars is ...
When a black hole chews up a star, it produces visible light or X-rays, but astronomers have almost never detected both types of radiation. Astronomer Peter Jonker (SRON/Radboud University) and his colleagues have now spotted a number of captured stars with an X-ray telescope a few years after they were discovered in optical light. It ...
