Earth may have had a giant ring of space rocks surrounding it, similar to those around Saturn, which could have led to chaotic meteorite strikes on our planet’s surface, new research suggests. The hypothesized ring may have formed roughly 466 million years ago and was the remains of a gigantic asteroid tugged apart by Earth’s … Read more
Data from India’s recent Chandrayaan-3 mission supports the idea that an ocean of molten rock once covered the moon. Scientists from the mission have published their new findings in the journal Nature. On August 23 2023, a lander called Vikram successfully touched down on the lunar surface. Controllers then deployed a rover called Pragyan, which … Read more
Scientists using the James Webb Space Telescope (JWST) have identified a component of water on the mysterious metal-rich asteroid Psyche. The findings suggest the hydration exists as rust and may shed light on how this enigmatic object formed. The asteroid 16 Psyche is pretty unusual for the main asteroid belt between Mars and Jupiter. Measuring … Read more
Mars is a planet of vast contrasts — huge volcanoes, deep canyons, and craters that may or may not host running water. It will be an amazing location for future tourists to explore, once we put the first Red Planet colonies into motion. The landing sites for these future missions will likely need to be … Read more
The Moon’s surface is pockmarked with more than 200 known pits where rocks and regolith collapsed into depths unknown. New research has found that one of those pits, in Mare Tranquillitatis, collapsed into a lava tube and made an underground cave conduit accessible from the lunar surface. “We found a sort of front door to … Read more
Microscopic wormholes may be driving the accelerated expansion of the universe, scientists say. These tiny wormholes are constantly being born from the vacuum of space due to subtle quantum effects. If confirmed through experiments and observations, the wormholes could become a valuable source of information on quantum gravity — a theoretical unification of the fundamental … Read more
The Milky Way is just a speck in a universe filled with an untold number of galaxies. But if we had to take an educated guess, how many galaxies are in the universe? That sounds like a simple question, but it’s anything but. The first problem is that even with our most powerful telescopes, we … Read more
Black holes are massive, mostly invisible and so powerful not even light can escape them. So what would happen if one entered our solar system? It depends on a lot of factors, including the size and distance of the black hole, experts told Live Science. But in many scenarios, not much would happen.”They’re not, per … Read more
Only about 600 people have ever traveled to space. The vast majority of astronauts over the past six decades have been middle-aged men on short-duration missions of fewer than 20 days. Today, with private, commercial and multinational spaceflight providers and flyers entering the market, we are witnessing a new era of human spaceflight. Missions have … Read more
“Warp drives” used by super-advanced alien civilizations may create specific space-time ripples in their wake that we can spot from Earth, a new paper argues. However, the jury is still out on whether the faster-than-light technology is even possible to create in the first place. A warp drive is a hypothetical device that enables an … Read more
