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.

Astronomers are another step closer to solving the intriguing cosmic mystery of fast radio bursts. Five signals have been traced to their points of origin within the spiral arms of galaxies, narrowing down the list of suspects behind them.
-
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.
-
On a scale that’s hard to fathom, the universe is structured like a “cosmic web." Astronomers have now directly observed light from filaments in this web, by staring at a patch of sky with a deep-field telescope to detect faint dwarf galaxies.
-
Astronomers using Hubble to hunt for an elusive type of black hole have stumbled onto a weirder scene. In the center of a nearby globular cluster, they discovered what looks like a whole gang of small black holes being uncharacteristically chummy.

How many galaxies are there in the observable universe? Not as many as we thought, according to a new study. NASA’s New Horizons probe has measured the blackness of the sky and found that there’s probably “only” a few hundred billion faint galaxies.

NASA has released a collection of 50 stunning Hubble images to celebrate the veteran telescope’s 30th anniversary, which took place earlier this year. The images show 30 cosmic objects, visible to amateur astronomers across the globe.
-
Planetary nebulae are basically slow-motion explosions in space, expected to expand and then fade over tens of thousands of years. But in an unprecedented show, Hubble has witnessed a nebula fading and shrinking dramatically within just 20 years.
-
Astronomers are a step closer to solving a cosmic mystery, thanks to new Hubble data. Observations show a dwarf galaxy previously found to be missing most of its dark matter is being stripped and slowly torn apart by a larger nearby galaxy.

A short burst of gamma rays 5.47 billion light years from Earth caused by the collision of two neutron stars that put out more energy in a half-second than the Sun could in 10 billion years has revealed the truth about luminous infrared kilonova.
-
A new “Sonification” project from NASA's Chandra X-ray Center has translated visual data into sound, letting us hear the center of the Milky Way, the supernova remnant Cassiopeia A, and the Pillars of Creation nebula.

It’s human nature to be transfixed by clouds, and Jupiter offers some of the best cloud-watching in the solar system. Now, new Hubble images remind us why, revealing fresh storms brewing along with some intriguing changes to old ones.
