New ‘eyewear’ to deepen the view of NASA’s Roman Space Telescope

NASA’s Nancy Grace Roman Space Telescope will be able to explore even more cosmic questions, thanks to a new near-infrared filter. The upgrade will allow the observatory to see longer wavelengths of light, opening up exciting new opportunities for discoveries from the edge of our solar system to the farthest reaches of space.

Hoinga: Debris of stellar explosion found in unexpected location

In the first all-sky survey by the eROSITA X-ray telescope onboard SRG, astronomers at the Max Planck Institute for Extraterrestrial Physics have identified a previously unknown supernova remnant, dubbed “Hoinga.” The finding was confirmed in archival radio data and marks the first discovery of a joint Australian-eROSITA partnership established to explore our Galaxy using multiple wavelengths, from low-frequency radio waves to…

International Space Station archives fuel new scientific discoveries

When scientists complete an experiment aboard the International Space Station, the ramifications of that work have just begun. NASA carries on a legacy of decades of biological research data, fueling new discoveries long after studies wrap up in space.

What is a quasar?

A quasar is an extremely bright and distant point-like source visible to radio telescopes. The source is a so-called Active Galactic Nucleus, fueled by a supermassive black hole. Source: https://earthsky.org/astronomy-essentials/definition-what-is-a-quasar…

Greek ship carrying parts of the Parthenon is giving up more secrets

The latest expedition by divers to the wreck of the Mentor, which sank just off the island of Kythera (also spelled Kithira and Kythira) in 1802, has recovered several pieces of the ship's rigging, coins, the leather sole of a shoe, a metal buckle, a token for playing cards, two chess pieces, fragments of cooking… Continue reading Greek ship carrying parts of the Parthenon is giving up more secrets

‘Earth wind’ may generate water on the moon

Magnetic effect without a magnet

Electric current is deflected by a magnetic field—in conducting materials, this leads to the so-called Hall effect. This effect is often used to measure magnetic fields. A surprising discovery has now been made at TU Wien, in collaboration with scientists from the Paul Scherrer Institute (Switzerland), McMater University (Canada), and Rice University (U.S.): an exotic metal made of cerium, bismuth and…

James Webb Space Telescope – Hubble’s successor – to launch in October

The James Webb Space Telescope is the world’s most complex infrared telescope, built for a wide range of research projects. NASA is now targeting October 31 for its launch on an Ariane 5 rocket from French Guiana. Source: https://earthsky.org/space/james-webb-telescope-hubble-successor-to-launch…
