A groundbreaking study by Chalmers University scientists reveals unprecedented molecular details in two early-universe galaxies, advancing our understanding of their star-formation activities.

Two galaxies in the early universe, which contain extremely productive star factories, have been studied by a team of scientists led by Chalmers University of Technology in Sweden. Using powerful telescopes to split the galaxies’ light into individual colors, the scientists were amazed to discover light from many different molecules – more than ever before at such distances. Studies like this could revolutionize our understanding of the lives of the most active galaxies when the universe was young, the researchers believe.

LST-1’s discovery of the distant quasar OP 313 at high energies marks a milestone in astronomy, highlighting the telescope’s advanced capabilities in exploring the farthest reaches of the universe.

On December 15, the Large-Sized Telescope (LST) Collaboration announced through an Astronomer’s Telegram (ATel) the detection of the source OP 313 at very high energies with the LST-1. Although OP 313 was known at lower energies, it had never been detected above 100 GeV, making this the LST-1’s first scientific discovery. With these results, OP 313 becomes the most distant Active Galactic Nuclei (AGN) ever detected by a Cherenkov telescope, further showcasing the LST prototype’s exceptional performance while it is being commissioned on the CTAO-North site on the island of La Palma, Spain.

The commercial space industry recently received a boost after NASA awarded 10 small businesses up to $150,000 each as part of NASA’s Small Business Innovation Research (SBIR) Ignite program, granting each company six months to demonstrate the viability and additional standards of their mission proposals. This funding comes as part of the second round of Phase I awards and holds the potential to continue the development of the commercial space industry for the short-and long-term.

“The investments we’re able to offer through SBIR Ignite give us the ability to de-risk technologies that have a strong commercial pull, helping make them more attractive to outside investors, customers, and partners,” said Jason L. Kessler, who is the Program Executive for the NASA SBIR & Small Business Technology Transfer (STTR) Program. “We also hope it advances the sometimes-overlooked goal of all SBIR programs to increase private-sector commercialization of the innovations derived from federal research and development funding.”

The 10 companies selected for this latest round of funding include (in alphabetical order): Astral Forge LLC, Astrobotic Technology Inc., Benchmark Space Systems, Brayton Energy LLC, Channel-Logistics LLC dba Space-Eyes, GeoVisual Analytics, Lunar Resources Inc., Space Lab Technologies LLC, Space Tango, and VerdeGo Aero.

Meteorologists on Earth struggle to predict the weather, but what about scientists trying to predict the weather on exoplanets that are light-years from Earth? This is what a recently accepted study to The Astrophysical Journal Supplement hopes to unveil as an international team of researchers used data from NASA’s Hubble Space Telescope to conduct a three-year investigation into weather patterns on WASP-121 b, which is a “hot Jupiter” that orbits its star in just over one day and located approximately 880 light-years from Earth. This study holds the potential to not only advance our understanding of exoplanets and their atmospheres, but also how we study them, as well.

“The assembled dataset represents a significant amount of observing time for a single planet and is currently the only consistent set of such repeated observations,” said Dr. Quentin Changeat, who is an Honorary Research Fellow in the Department of Astronomy at University College London and lead author of the study. “The information that we extracted from those observations was used to infer the chemistry, temperature, and clouds of the atmosphere of WASP-121 b at different times. This provided us with an exquisite picture of the planet changing over time.”

New observations of the Small Magellanic Cloud show that it might actually be two galaxies disguised as one.

The Juno spacecraft’s instruments will help scientists better understand volcanic activity on the volatile moon’s surface.

A recent paper suggests our understanding of the cosmos is wrong and proposes a different model. Could this new idea be right? In a word: No.

The recently detected gravitational waves are a muddled mix of various sources, new study finds.

From robotic lunar landers perusing the surface to an astronaut flyby, 2024 could be the year NASA makes its big return to the moon.
