The Tarantula That Lost Its Fire

A new composite image combining data from Chandra, Hubble, Webb and the retired Spitzer telescope has helped astronomers solve a long standing puzzle in the Tarantula Nebula, a star forming region 160,000 light years away. Young, massive stars there should be heating enough gas to emit X-rays, but observations showed far less X-ray emission than predicted.

Largest Italian radio telescope located on an out of the way mountain plateau in southern Sardinia sheds light on the cosmos’ still misunderstood Fast Radio Bursts (FRBs).



Another First for the JWST: It Detects Three Supermassive Black Holes in the Same Galaxy

Astronomers working with the JWST have found a galaxy only 1.3 billion years after the Big Bang that contains three black holes. Two are close to the galaxy's center and will merge soon. The third is more distant, and is expected to merge much later. The discovery shows that black hole mergers were an important contributor to the masses of the SMBH we find in galaxies today.

A Rare Extragalactic Stellar Stream Reveals Hidden Dark Matter

Scientists have discovered a rare star formation hidden in a distant galaxy, unlike anything seen before beyond the Milky Way. What’s more, the discovery offers a brand new way to measure the distribution of dark matter in distant galaxies.



The Rooms We Build To Survive In, And The Ones We Build To Live In

What does a home actually need to do for us, beyond keeping the weather out? Engineers at MIT have started mapping the answer for astronauts heading to the Moon and Mars, tracing exactly how the walls, layouts and lighting around a person shape their stress, their loneliness and their sense of belonging. It turns out the science of surviving a place and the science of living in one are not the same thing at all, and I have spent enough of the last year thinking about that difference to know how much it matters.



The Ingredients For Planets Turned Up Astonishingly Early

Planet building was supposed to be one of the universe's slow projects, something that only got going billions of years after the Big Bang. New research suggests otherwise. The raw materials for rocky worlds, and perhaps even the water needed for life, may have been ready to go just 100 million years after the Big Bang, long before the first galaxies had even taken shape.



A Massive Stream of Gas Tilted This Planet-Forming Disk

Astronomers found evidence that a giant stream of gas flowing into the GW Orionis young triple-star system may have tilted its planet-forming disk, offering a new explanation for why some planetary systems are misaligned. The next step is to search for shock fronts in the system, and to search for more of these massive streams of gas in other systems.
