Jupiter’s large size and cool core make it an excellent target in the search for dark matter. A team of scientists is analyzing gamma-ray data from the Fermi Telescope looking for signs of the elusive substance.
The unexpected discovery of yellowballs by citizen scientists – in 2011 and 2012 – is shaking up astronomers’ ideas about how stars and star clusters form. It’s giving scientists a new window into the birth and evolution of young stars.
NASA has given the name Rafael Navarro Mountain to a hill in Gale Crater on Mars, where the Curiosity rover has been exploring since 2012. Navarro, a mission scientist, died in January 2021 from Covid-19.
A new analysis of data from the 1978 Pioneer Venus mission, by researchers at Cal Poly Pomona, finds evidence not only for phosphine, but also possible chemical disequilibrium in Venus’ atmosphere, an additional possible sign of biological activity.
NASA’s Juno spacecraft – whose mission in orbit around Jupiter was recently extended to 2025 – has been used to discover a rapidly expanding auroral ring at the very fringes of the Jovian magnetosphere.
An international team of astronomers has mapped a piece of the cosmic web without using bright quasars for the first time. They did it by turning a powerful instrument to a single region of the sky for hundreds of hours.
Data from ESA’s Gaia star-mapping satellite have revealed tantalizing evidence that the famous V-shaped Hyades – nearest star cluster to our sun – is being disrupted. The culprit may be a suspected population of dark matter sub-halos. Wow!
Comet 2I/Borisov is the 2nd known object to pass near our sun from outside our solar system. Its 2019 pass near our sun might have been its first-ever interaction with a star. If so, it’s among the most pristine, or unspoiled, objects yet known.
Astronomers have detected a “Goldilocks” or intermediate-mass black hole. It’s not small, not supermassive – but right in the middle – and it “sheds light” on how the supermassive black holes got so large.
When the TESS planet hunter launched nearly 3 years ago, some 4,000 exoplanets were known. NASA confirmed in late March that TESS has discovered over 2,200 additional exoplanet candidates orbiting distant stars.
Apophis’ flyby in early March 2021 enabled astronomers to conclude there’s no chance this asteroid will strike Earth anytime soon. “A 2068 impact is not in the realm of possibility anymore,” one scientist said, “and our calculations don’t show any impact risk for at least the next 100 years.”
