Hubble Follows Sneaky Shadow Play Around Planet-Forming Disk

The young star TW Hydrae is playing “shadow puppets” around the planet-forming disk with scientists observing it with NASA’s Hubble Space Telescope. In 2017, astronomers reported discovering a shadow sweeping across…

New Study of Uranus’ Large Moons Shows 4 May Hold Water

The new modeling explores how oceans could exist in unlikely places in our solar system, such as distant moons around other planets. Uranus is surrounded by its four major rings…

Mass monster M87 with the cosmic digestive system

New observations of the spectacular M87 galaxy reveal how a powerful jet forms around a monstrous black hole contained inside it. The Giant Galaxy Around the Giant Black Hole: The…

Neutron star’s X-rays reveal the beauty of ‘photon metamorphosis’

A “beautiful effect” predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar – a neutron star featuring a powerful magnetic field,…

Mysterious flashes: Now we have double the number of known ‘repeating fast radio bursts’

Astronomers in the Canadian-led CHIME/FRB Collaboration – including researchers from the University of Toronto – have doubled the number of known repeating sources of mysterious flashes of radio waves, known as…

New map of the universe’s cosmic growth supports Einstein’s theory of gravity

Cosmic growth: unlike ancient philosophers imagining the universe’s origins, modern cosmologists use quantitative tools to gain insights into its evolution and structure. Modern cosmology dates back to the early 20th…

Doubling the number of sources of repeating fast radio bursts

Astronomers from McGill University are part of an international team that has discovered 25 new sources of repeating fast radio bursts (FRBs), these explosions in the sky come from far…

Metal-poor stars are more life-friendly

Stars that contain comparatively large amounts of heavy elements provide less favourable conditions for the emergence of complex life than metal-poor stars, as scientists from the Max Planck Institutes for…
