A large asteroid once considered the greatest known risk to Earth may now be on track for a direct hit — not on our planet, but on the moon. The object, named asteroid 2024 YR4, has drawn intense interest from the astronomy community as its trajectory evolves, raising questions about potential consequences for lunar infrastructure and even Earth-orbiting satellites. From …

There is an asteroid approximately the size of a building that has been on the radar of many astronomers for a long time due to its initial potential to collide with the Earth. However, there is no need to worry anymore, as its trajectory has shifted slightly since it was first detected. It is now expected to miss the Earth …

The molecules that form the building blocks to life may be far more common in space than once thought, according to researchers from the Max Planck Institute. Their work, published in The Astrophysical Journal, reports the detection of over a dozen types of complex organic molecules swimming closely around a protostar in the constellation Orion, suggesting that the chemicals can …

NASA has discovered a massive gold deposit on asteroid 16 Psyche, a metallic-rich body located in the asteroid belt. This asteroid is estimated to contain $700 quintillion worth of metals, including gold, iron, and nickel, reports The Pulse. With such a colossal value, this discovery has the potential to transform humanity’s understanding of resource wealth in the cosmos, though the …

Next time you’re drinking a frosty iced beverage, think about the structure of the frozen chunks chilling it down. Here on Earth, we generally see ice in many forms: cubes, sleet, snow, icicles, slabs covering lakes and rivers, and glaciers. Water ice does this thanks to its hexagonal crystal lattice. That makes it less dense than nonfrozen water, which allows …

The Hubble Space Telescope has snapped some spooky looking photos of our solar system’s newest interstellar invader on the run. The object, dubbed 3I/ATLAS, was first spotted careening through the outer limits of the Sun’s domain earlier this month, and appears to be a comet. Upon closer inspection, its speed was found to be so incredible that there could be …

In an intriguing turn of events, scientists have been exploring the possibility of adding the first-ever negative leap second. This comes after significant changes in Earth’s rotation speed, which has been accelerating since 2020. For instance, July 9 and July 22 of this year were recorded as unusually short days, losing roughly 1.3 and 1.4 milliseconds, respectively. As we move …

Recent NASA budget uncertainties could make one space agency endeavor up for grabs — defending Earth from incoming space rocks. That effort, undertaken by NASA for many years, could be given to the U.S. Space Force, which has a much bigger new budget. On the other hand, is a Space Force takeover of taking out potentially dangerous asteroids warranted, and …

A fascinating new study has shaken up our understanding of Earth’s oceans. It reveals that around 15 million years ago, something remarkable happened beneath the surface of the planet: the Earth “swallowed” billions of tonnes of water, causing sea levels to drop by a staggering 30 meters. This discovery, published in February 2025 on the AGU portal by researchers looking …
