Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed.

Some humans have already had a chance to visit space purely for fun. But will that be attainable for regular people anytime ...

If a star orbits a black hole, it will appear from a distance to be orbiting empty space. Gaia projects the star’s orbit on a ...

Black holes are as dangerous as they are distant, so scientists set out to simulate one in a lab. What happened next would ...

In a seemingly reverse Titanic reenactment, the world’s largest iceberg is heading straight for a remote British territory—one teeming with sensitive wildlife. The colossal iceberg A23a is on ...

In a way, we've achieved escape velocity on parts of the climate journey. The shift to cleaner, cheaper, more reliable power on the grid—I think that is a secular and sustained trend in the ...

Policy experts say President Joe Biden can rightly claim to have meaningfully reduced carbon emissions and boosted clean energy. But will those policies last?

He’s promised to restore the company’s culture and regain a leadership position. That effort has struggled to achieve escape velocity thanks to the recent crash of a 737 in South Korea that, while not ...

There’s a reason why a rocket has to go so fast to escape Earth. It’s about gravity – something all of us experience every moment of every day. A SpaceX Falcon 9 rocket with its Crew Dragon capsule ...

Seismology is the study of stress and changes in stress within the Earth and other planetary bodies ... shallow bubble escape dynamics, and tremor changes.

Scientists call that speed the escape velocity. A rocket needs to go that fast so that the momentum propelling it away from Earth is stronger than the force of gravity pulling it back. Any slower ...
