Neutron stars: Mysterious object blasts out radio waves every 18 minutes

Something extraordinarily bright in space is pulsing far slower than most similar cosmic objects, and it may be a strange type of neutron star that we have never seen before Space 26 January 2022 By Leah Crane A view of the Milky Way from the Murchison Widefield Array. The star icon shows the position of … Read more

Strange gravitational wave echoes may let us probe dark matter

When gravitational waves pass over massive objects, they should create an echo that could allow us to examine objects that we can’t otherwise see, including dark matter Space 27 January 2022 By Leah Crane An illustration of gravitational waves Shutterstock The entire universe is suffused with gravitational waves, ripples in space-time caused by the motion … Read more

Astronomers Detect Strange Signals We’ve Never Seen Before in Our Cosmic Vicinity

Something in Earth’s cosmic neighborhood is emitting weird signals of a kind we’ve never seen before. Just 4,000 light-years away, something is flashing radio waves. For roughly 30 to 60 seconds, every 18.18 minutes, it pulses brightly, one of the most luminous objects in the low-frequency radio sky. It matches the profile of no known … Read more

Can you see stars in light polluted skies?

Light pollution is a big problem, and it’s getting bigger. Recently published research led by Dr Alejandro Sánchez de Miguel at the University of Exeter, UK suggests that a global rise in artificial lighting has substantially boosted light pollution levels over the past few decades – some regions have suffered as much as a fivefold increase! … Read more

Astronomers Detect Rare ‘Missing Link’ Black Hole in Our Closest Galactic Neighbor

A rare treasure that could shed light on the evolution of black holes has been discovered in the Milky Way’s closest large galactic neighbor. In a cluster of stars in the Andromeda galaxy, aka M31, astronomers studied changes in light to identify a black hole clocking in at almost 100,000 times the mass of the … Read more

Hubble telescope spots a black hole fostering baby stars in a dwarf galaxy

Black holes can not only rip stars apart, but they can also trigger star formation, as scientists have now seen in a nearby dwarf galaxy. At the centers of most, if not all, large galaxies are supermassive black holes with masses that are millions to billions of times that of Earth’s sun. For instance, at … Read more
