Astronomers already knew that our own Milky Way grew by taking in smaller galaxies. But now a team of Italian-Dutch researchers have shown that a small galaxy neighbouring the Milky Way has in turn absorbed an even smaller galaxy from its vicinity. The researchers will publish their findings on Monday in the journal Nature Astronomy. According to the prevailing theory, large galaxies such

White dwarfs are what most stars become after burning off the hydrogen that fuels them. Now our astronomers have seen one of these galactic objects switching on and off for the first time. Researchers used a planet-hunting satellite to observe the unique phenomenon in a white dwarf about 1,400 light years from Earth. This particular white dwarf is known to be accreting, or feeding, f

Astronomers at Queen's University Belfast have launched a new online initiative, calling for volunteers to come forward and help to search for extrasolar planets. The online citizen project, hosted by Zooniverse.org, Planet Hunters Next-Generation Transit Search (NGTS), is enlisting the help of the public to examine five years' worth of digital footage showing some of the brightest stars i

Thanks to two microphones aboard NASA's Perseverance rover, the mission has recorded nearly five hours of Martian wind gusts, rover wheels crunching over gravel, and motors whirring as the spacecraft moves its arm. These sounds allow scientists and engineers to experience the Red Planet in new ways - and everyone is invited to listen in. "It's like you're really standing there," said Bapti

New methods of detecting ultra-low frequency gravitational waves can be combined with other, less sensitive measurements to deliver fresh insights into the early development of our universe, according to researchers at the University of Birmingham. Gravitational waves - ripples in the fabric of Einstein's spacetime - that cross the universe at the speed of light have all sorts of wavelengt

White House Press Secretary Jen Psaki on Monday declined to comment on a report claiming that China tested a nuclear-capable hypersonic missile in August. "I'm not going to comment on the specific report," Psaki said when asked if she could confirm the report that China tested a nuclear-capable hypersonic missile this summer that surprised US officials. Psaki reiterated Defense Secre

Their movie props floated around and they used Velcro to keep objects in place but Russia's first film crew in space said they were delighted with the result and had "shot everything we planned". Yulia Peresild, one of Russia's most glamorous actresses, and film director Klim Shipenko returned to Earth on Sunday after spending 12 days on the International Space Station (ISS) shooting the fir

A Dunlap Institute astronomer has discovered that our solar system may be surrounded by what she describes as a magnetic tunnel that can be seen in radio waves. Dr. Jennifer West, Research Associate at the Dunlap Institute for Astronomy and Astrophysics, is making a scientific case that two bright structures that are seen on opposite sides of the sky - previously considered to be separate

The first lunar rocks brought back to Earth in decades show the Moon was volcanically active more recently than previously thought, Chinese scientists said Tuesday. A Chinese spacecraft carried lunar rocks and soil to Earth last year - humanity's first mission in four decades to collect samples from the Moon, and a milestone for Beijing's growing space programme. The samples included ba

An international team of physicists led by researchers at Indiana University has announced the world's most precise measurement of the neutron's lifetime. The scientific purpose of the experiment, which IU has led for over a decade, is to measure how long, on average, a free neutron lives outside the confines of atomic nuclei. The results from the team, which encompasses scientists f
