Live in the eastern hemisphere? If skies are clear, you have a chance to see a remarkable sight this Sunday night into Monday morning: the ‘Blood Moon’ of a total lunar eclipse. The eclipse favors the Indian Ocean region in its entirety. Europe sees the eclipse already underway at Moonrise, while Australia catches it in progress at Moonset. Only the Americas sit this one out in person... though you can still catch it live online.

One of the most difficult parts of astronomy is understanding how time affects it. The farther away you look in the universe, the farther back you look in time. One way this complicates things is how objects might change over time. For example, a supermassive black hole at the center of a galaxy in the early universe might appear one way to our modern telescopes, but the same supermassive black hole might appear completely differently a few billion years later. Understanding the connection between the two objects would be difficult to say the least, but a new paper from researchers at the University of Science and Technology in South Korea describes one potential parallel, between the recently discovered “Little Red Dots” of the early universe and “BlueDOGs” of the slightly later universe.

Hurricane activity in the Atlantic basin is historically at its peak on September 10—but not this year

A single tick bite can trigger a bizarre meat allergy—here’s how alpha-gal syndrome is reshaping people’s diets.

"The profile of the occultation was most consistent with it being a new satellite — a new moon — going around Quaoar."

It has long been claimed that only one mammal – the golden mole – has fur that shimmers with rainbow colours, but it now turns out that at least a dozen more mammals have iridescent fur too

How soon do jets form when a supernova gives birth to a neutron star?

IMAP data "will help us better understand the fundamental physics of the heliosphere."

"If this is a massive star, it is a collapse unlike anything we have ever witnessed before."

An international team of astronomers led by Matus Rybak (Leiden University, Netherlands) has proven, thanks to accidental double zoom, that millimetre radiation is generated close to the core of a supermassive black hole. Their findings have been accepted for publication in the journal Astronomy & Astrophysics.

The so-called Butterfly star gets its name from its edge-on appearance. The star's protoplanetary disk blocks out starlight revealing a nebula, or butterfly wing, on each side. Deeper JWST observations show the disk is tilted and asymmetrical, which affects how planets form.

Water is key to life as we know it. But that doesn’t mean its key to life everywhere. Despite the fact that the ability to house liquid water is one of the key characteristics we look for in potentially habitable exoplanets, there is nothing written in stone about the fact that life has to use water as a solvent as opposed to other liquid options. A new paper from researchers at MIT, including those who are developing missions to look for life on Venus, shows there might be an alternative - ionic liquids that can form and stay stable in really harsh conditions.

Images taken with the MIRI infrared camera on the James Webb Space Telescope (JWST) have made it possible to observe the first galaxies in long-wavelength infrared light for the first time. Alongside a recent study published in Astronomy and Astrophysics, these images provide new insights into how the first galaxies formed over 13 billion years ago.

A monumental sign of an atmosphere on TRAPPIST-1e could be the precursor to finally finding a living world around another star

Some cosmic events could have profoundly altered the lives of our ancient human relatives. Did Neanderthals go extinct, at least in part, due to changes in Earth’s magnetic field? Did Australopithecus witness huge meteorite impacts?
