Having someone in your life who hassles you or causes problems could be adding 2.5 months to your biological age

It has been claimed Neanderthals ate a huge amount of meat based on isotope ratios in their bones – but the explanation could instead be a diet rich in maggots

Rising temperatures are causing water to evaporate and driving humans to extract more groundwater, which is moving freshwater from the land to the seas and creating a "continental drying" trend

The four members of SpaceX's Crew-10 mission on the Expedition 73 crew began packing for home, while also calling down to Earth to share their ongoing work aboard the ISS.

Unlike other superhero superstars, the Fanastic Four have traditionally struggled with the transition to the big screen.

Crew-11 will launch from NASA's Kennedy Space Center in Florida on July 31 atop a Falcon 9 rocket, if all goes to plan.

Blue Origin has announced the payload for the first-ever flight of its Blue Ring spacecraft —Scout Space's Owl space domain awareness sensor.

Tens of millions of people are already under heat alerts, and the worst is yet to come

A new image from the Gemini Observatory might show a stellar companion to Betelgeuse, but the discovery is tentative.

The post Betelgeuse's Companion Has Been Found — Or Has It? appeared first on Sky & Telescope.

NASA currently leads the nation's planetary defense efforts, but some are calling for the Space Force to take control.

Every time a spacecraft touches down on the moon, it creates a spectacular but dangerous light show of dust and debris that could threaten future lunar bases. Now, after decades of mystery, scientists have finally figured out why these dust clouds form such distinctive patterns and the answer could be crucial for humanity's return to the Moon.

Scientists have created the largest catalogue of exploding stars ever assembled, and it's telling us something surprising about the mysterious force driving our universe apart. After analyzing over 2,000 stellar explosions spanning billions of years, researchers have found hints that dark energy, the force making up 70% of our universe, may not be the constant we once thought. Instead, it appears to be changing over time, potentially even weakening!

Recreating the environment that most spacecraft experience on their missions is difficult on Earth. Many times it involves large vacuum chambers or wind tunnels that are specially designed for certain kinds of tests. But sometimes, engineers get to just do larger scale versions of the things they got to do in high school. That is the case for a recent test of ExoMars’s parachute system. A team of ESA engineers and their contractors performed a scaled up egg-drop test common in physics classes across the world. Except this one involved a stratospheric balloon the size of a football field and a helicopter.

NASA's Transiting Exoplanet Survey Satellite (TESS) detected three rocky planets around the M-dwarf L 98-59 in 2019. While two are expected to be hot, rocky worlds, the third could be covered by a global ocean. A fourth planet was discovered in 2021, and now, additional study has revealed a fifth planet, a super-Earth in the star's habitable zone.

While all the technology of the Apollo program still exists in the form of blueprints and designs, all the human expertise that went into crafting those rockets and spaceships is now either retired or passed away.
