‘Absolutely gutted’: How a jammed door is locking astronomers out of the X-ray universe
Just outside Hiroya Yamaguchi’s office is a blackboard crowded with exploded stars, spaceship schematics and spectral lines. The A4 printouts obscure almost all the free space, except for a tiny corner where he sometimes scribbles in white chalk. Right now, Yamaguchi, an associate professor at Japan’s Institute of Space and Astronautical Science, is standing in…

An interstellar cloud may have caused an ice age on Earth. Here’s how
Scientists believe Earth may have briefly lost protection from the sun around two million years ago, left to endure the extreme environment of interstellar space as the solar system passed through a dense cloud of gas and dust between stars. At that time, early human ancestors shared our planet with prehistoric animals like mastodons and…

🔭 This unusual regular signal from space leaves astronomers without explanation
When astronomers point their radio telescopes towards space, they sometimes detect sporadic bursts of radio waves from the Universe. These phenomena, known as “radio transients,” can sometimes appear only once, and sometimes in regular cycles. Possible location of the radio source. The majority of radio transients come from pulsars, which are neutron stars spinning at…

Astronomers use JWST to peer into the heart of the Crab Nebula
The Crab Nebula, the remnant of a supernova observed in 1054 AD by Chinese astronomers, has long been one of the most famous space structures. Now, with the James Webb Space Telescope (JWST), astronomers have imaged the nebula in unprecedented detail. The new data provides insights into the pulsar wind, dusty filaments, and the elemental…

Landolt space mission: more precise measurements of star brightness
Jonathan Gagné Credit: Courtesy A major scientific breakthrough will be taking place soon thanks to NASA’s Landolt space mission. The mission, at a cost of $19.5 million, will make it possible to measure stellar luminosities more accurately. Jonathan Gagné, scientific advisor at the Montreal Planétarium, adjunct professor at Université de Montréal and member of the…

James Webb telescope finds carbon at the dawn of the universe, challenging our understanding of when life could have emerged
The James Webb Space Telescope (JWST) has detected a key building block of life at the dawn of the universe, upending what we know about the first galaxies. The discovery — a cloud of carbon in a distant and compact galaxy as it appeared just 350 million years after the Big Bang — marks the…

What’s causing a weird, repeating signal from space? Astronomers are stumped.
CSIRO’s ASKAP radio telescope Credit: Carl Knox/OzGrav When astronomers turn our radio telescopes out towards space, we sometimes detect sporadic bursts of radio waves originating from across the vast expanse of the universe. We call them “radio transients”: some erupt only once, never to be seen again, and others flicker on and off in predictable…
