Astronomers spot “invisible” galaxies at the dawn of the universe

Astronomers have spotted two “invisible” galaxies hiding near the dawn of the universe. The team used radio waves to peer behind a curtain of dust that was obscuring them from view, and the find suggests that there were far more galaxies in the early u… Continue reading Astronomers spot “invisible” galaxies at the dawn of the universe

Stunning snaps from Hubble’s latest grand tour of the outer solar system

Every year, the Hubble Space Telescope conducts a grand tour of the outer solar system planets, checking their turbulent atmospheres for changes in weather, storms, clouds and colors. This year’s shots are now in, revealing a few surprises.Continue Rea… Continue reading Stunning snaps from Hubble’s latest grand tour of the outer solar system

The light galaxy at the heart of a dark dispute

Dark matter is considered the glue that holds galaxies together – but a few years ago, a team of astronomers claimed to have found a galaxy that didn’t have any. Other scientists later argued it was a calculation error, but now the original team has us… Continue reading The light galaxy at the heart of a dark dispute

Astronomers conclude Betelgeuse isn’t dying, it’s just dusty

Astronomers say they’ve closed the case on the mysterious and unprecedented dimming of the supergiant star Betelgeuse in 2019 and 2020. A new study says that the event was caused by a combination of a big dust cloud and a drop in temperature.Continue R… Continue reading Astronomers conclude Betelgeuse isn’t dying, it’s just dusty

Five fast radio bursts tracked to home galaxies

Astronomers are another step closer to solving one of the most intriguing cosmic mysteries of recent times – fast radio bursts (FRBs). A team has now traced five signals to their points of origin within the spiral arms of galaxies, narrowing down the l… Continue reading Five fast radio bursts tracked to home galaxies

Powerful protostars may not be responsible for ending their own growth

Fresh research has cast doubt on the theory that energetic outbursts from young stars blows away the cocoon of gas from which they formed, which in turn prevents them from growing any further. The Milky Way plays host to over 200 billion stars, the ear… Continue reading Powerful protostars may not be responsible for ending their own growth
