World’s Most Powerful Millimeter/Submillimeter Telescope Captures Highest Resolution Observations—Ever
An international team of astronomers has collaborated to improve the capabilities of the Atacama Large Millimeter/submillimeter Array (ALMA), one of the world’s most powerful telescopes. Scientists from the National Science Foundation’s National Radio Astronomy Observatory (NRAO), the Joint ALMA Observatory, the National Astronomical Observatory of Japan (NAOJ), and European Southern Observatory have achieved the highest…

Astronomers pierce cosmic dust to study the anatomy of a dying star
Astronomers with the Gemini North Telescope on Mauna Kea in Hawaii have released the first spectrum from a brand new spectrograph capable of peering deep into the veils of cosmic dust that line our universe. The spectrum shows details of an expanding cloud of gas and dust that a sun-like star ejected at the end…

Webb Shows Planets Really Do Start with Pebbles
This artist’s concept compares two types of typical, planet-forming disks around newborn, Sun-like stars. On the left is a compact disk, and on the right is an extended disk with gaps. Scientists using Webb recently studied four protoplanetary disks — two compact and two extended. The researchers designed their observations to test whether compact planet-forming…

Second-most distant galaxy discovered using James Webb Space Telescope
UNIVERSITY PARK, Pa. — The second- and fourth-most distant galaxies ever observed have been discovered in a region of space known as Pandora’s Cluster, or Abell 2744, using data from NASA’s James Webb Space Telescope (JWST). Following up on a deep field image of the area, an international team led by Penn State researchers confirmed…

Lost in space: $100,000 tool bag from NASA spacewalk
Nov. 13 (UPI) — Every construction worker who ever accidentally left their tools at their worksite now has something in common with NASA astronauts, who lost a tool bag worth $100,000 during a spacewalk on Nov. 1, the space agency announced. The white satchel, which can now be seen orbiting the Earth with a telescope…

GSOA publishes space sustainability Code of Conduct
The report calls on operators to implement responsible practices that mitigate the risk of in-orbit collision, minimise the threat of non-trackable debris, protect humans in space and limit effects on optical astronomy. “Satellites in all orbits deliver vital satellite connectivity and high throughput broadband services. While they offer great promises in bridging the digital divide,…

Using eclipses to calculate the transparency of Saturn’s rings
A Lancaster University PhD student has measured the optical depth of Saturn’s rings using a new method based on how much sunlight reached the Cassini spacecraft while it was in the shadow of the rings. The optical depth is connected to the transparency of an object and a measure of how far light can travel…

How Aditya L-1 is helping in detecting and monitoring solar flares?
The Indian Space Research Organisation (ISRO) recently announced that it had reached a groundbreaking milestone in solar research when its High-Energy L1 Orbiting X-ray Spectrometer (HEL1OS) aboard India’s first solar space observatory, Aditya L1, “recorded the impulsive phase of a high-energy solar flare” during its maiden observation on October 29, 2023. HELIOS was developed by…
