Astronomers see cataclysmic collision of giant asteroids in nearby galaxy

Nearly twenty years ago, astronomers observed a huge cloud of fine dust particles around a young star just 63 light-years away from Earth. From recent observations of the Webb Space TelescopeHowever, the dust cloud had mysteriously disappeared. Now a new paper suggests that the dust cloud may have been caused by a violent event that … Read more

Radio astronomers are sounding the alarm bells about SpaceX’s cellular Starlink technology

SpaceX and AST SpaceMobile are working to bring satellite connectivity to smartphones, but scientists say the technology threatens to disrupt radio astronomy. “The proposed direct-to-cell satellites would effectively eliminate the existence of radio silence zones, significantly reducing the effectiveness of existing radio telescopes,” said Catherine Lovekin, associate professor of physics at Mount Allison University in … Read more

Astronomers want to look for terraformed ‘snowball’ Earths

Illustration of the Earth, with the continents in their current form, but with the planet complete … [+] frozen. The snowball Earth hypothesis suggests that the Earth may have frozen in this way hundreds of millions of years ago due to severe climate change. This illustration represents what the planet would look like if this … Read more

Astronomers discover the largest planet-forming disk we’ve ever seen

About 1,000 light-years from Earth lies a cosmic structure known as IRAS 23077+6707 (IRAS 23077), which resembles a giant butterfly. Ciprian T. Berghea, an astronomer at the US Naval Observatory, originally observed the structure in 2016 using the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS). To the surprise of many, the structure has remained … Read more

Newly discovered exoplanet could have temperatures similar to Earth, astronomers suggest

A newly discovered exoplanet, estimated to have a remarkably moderate surface temperature, is suddenly one of the most intriguing objects in our immediate sky. This Venus-sized rocky world passes by a red dwarf star, offering astronomers a rare opportunity to investigate whether such planets can maintain their atmospheres and possibly support life. How will time … Read more
