NASA’s Carruthers Observatory Begins Mission to Study Earth’s Hydrogen Halo
NASA’s Carruthers Observatory has begun its two-year science mission to study Earth’s hydrogen-rich exosphere from a halo orbit at Sun–Earth L1. Equipped with ultraviolet cameras, the small satellite will continuously image the faint geocorona, tracking how solar storms and fast solar wind streams cause the upper atmosphere to expand, contrac...

Hubble Reveals How Blue Straggler Stars Stay Young in Ancient Clusters
Astronomers using the Hubble Space Telescope have uncovered new clues to the mystery of blue straggler stars—unusually hot, bright stars found in ancient globular clusters. By studying ultraviolet light from 48 clusters, scientists discovered that blue stragglers are more common in sparse clusters, supporting the idea that they form through binar...

James Webb Space Telescope Finds Unexpected Ultraviolet Radiation Around Young Protostars
Astronomers using the James Webb Space Telescope have detected unexpected ultraviolet radiation around five young protostars in the Ophiuchus molecular cloud. Since infant stars are not expected to emit UV light, the finding challenges long-standing star-formation models. Researchers ruled out external illumination from nearby stars, concluding the...

NASA May Have Detected Oldest Stars In Universe Formed After Big Bang
NASA's James Webb Space Telescope may have detected the universe's oldest Population III stars in galaxy LAP1-B, 13 billion light-years away.

NASA Prepares 2025 Carruthers Mission to Explore Earth’s Hidden Hydrogen Halo
NASA’s Carruthers Geocorona Observatory, launching in 2025, will capture ultraviolet light from hydrogen atoms to map Earth’s faint geocorona. Operating a million miles sunward, it will study how solar activity drives atmospheric loss, improves satellite protection, and reveals clues to planetary habitability, providing critical insight for fut...

NASA Hubble Space Telescope Uncovers One of the Youngest Known Blue Straggler–White Dwarf Systems
Italian astronomers using the Hubble Space Telescope have discovered a white dwarf orbiting a blue straggler star in the globular cluster 47 Tucanae, located 15,300 light-years away. The rare system, among the youngest detected, sheds light on stellar mass transfer and offers vital clues to the evolution of binary stars in dense clusters.

James Webb Telescope Spots Planet Formation in Harshest Known Galactic Environments
The James Webb Space Telescope has revealed that planets can form in extreme radiation zones. A protoplanetary disk called XUE 1, exposed to intense ultraviolet light, still shows signs of water and potential for rocky planet formation. The findings challenge old assumptions and broaden the possible regions where Earth-like planets may emerge.

Is Mars Really Red? A Physicist Explains the Science Behind Its Colour and More
A physicist explains the science behind Mars’s red appearance, linking its hue to iron oxide or rust. While known as the Red Planet, rover images and telescope data show varied colors, from tan to white ice caps. Observations in ultraviolet and infrared light reveal deeper insights into Mars’s atmosphere, surface, and seasonal changes, enrichin...

ISRO’s AstroSat Observes First-Ever Nuclear Explosion in Andromeda Galaxy
Using the Ultraviolet Imaging Telescope (UVIT) aboard ISRO’s AstroSat, scientists have identified far-ultraviolet emissions from 42 novae in the Andromeda Galaxy. This marks the first detection of such emissions during their outbursts, offering new insights into the processes of stellar explosions. Four of these novae were observed in real-time a...
