Happy New Year on Mars (Image Credit: Phys.org) To mark 20 years of ESA’s Mars Express, the High Resolution Stereo Camera (HRSC) team has produced a new global colour mosaic: Mars as never seen before. The mosaic reveals the planet’s surface colour and composition in spectacular detail. Credit: ESA/DLR/FU Berlin/G. Michael 12 […]
Recent studies question the theory of dark matter in relation to galaxy formation.
New research challenges dark matter theory in galaxy formation (Image Credit: Phys.org) Protogalaxies as seen by the James Webb Space Telescope. Credit: NASA The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data […]
Astronomers study the long-term changes in the blazar AO 0235+164.
Astronomers investigate long-term variability of blazar AO 0235+164 (Image Credit: Phys.org) Comparison of the AO 0235+164 R-magnitudes taken with both optical telescopes (x-axis: Zeiss-1000, y-axis: AS-500/2). Credit: arXiv (2024). DOI: 10.48550/arxiv.2411.01497 Astronomers have performed a comprehensive multiwavelength study of an extremely variable blazar known as AO 0235+164. Results of the new study, […]
Currently, the sun is more active than expected, and small satellites are bearing the consequences.
Right now, the sun is far more active than predicted—and small satellites are paying the price (Image Credit: Phys.org) Credit: Pixabay/CC0 Public Domain Last week, three tiny Australian satellites from Curtin University’s Binar Space Program burned up in Earth’s atmosphere. That was always going to happen. In fact, Binar means “fireball” in […]
Researchers discovered ‘nitriles’ in an interstellar cloud — here’s why this could be significant.
Scientists found ‘nitriles’ in an interstellar cloud — here’s why that could be huge (Image Credit: Space.com) In the Taurus molecular cloud, one of the closest stellar nurseries to Earth, scientists found two nitrile-containing molecules — and this is incredibly interesting because these very molecules could reveal information about the origins of […]
The mysteries of a black hole may be concealed in its swirling light ‘reflections.’
A black hole’s secrets could hide in its dizzying light ‘echoes’ (Image Credit: Space.com) To measure the masses and spins of black holes, scientists want to follow clues left behind by light that takes a round-a-bout journey, bends around these voids, and ultimately shines toward us. The crew, from Princeton University and […]
Trump’s re-election might rekindle the debate over the Space Command headquarters.
Trump’s Re-Election Could Reignite Battle Over Space Command Headquarters (Image Credit: Gizmodo-com) Despite a months-long battle that finally settled the U.S. Space Command in Colorado, the military branch may be at risk of relocating to Alabama once again. President-elect Donald Trump is expected to move the Space Command headquarters to Huntsville, Alabama, […]
Voyager found a mystery on Uranus. Decades later, NASA solved it. (Image Credit: Mashable) NASA’s Voyager mission beamed back unprecedented views. It also sent back some mysteries. One of these came in 1986, when the Voyager 2 probe — one of a duo of Voyager craft sent into deep space — journeyed […]
