It's easy to take time's arrow for granted - but the gears of physics actually work just as smoothly in reverse. Maybe that time machine is possible after all?

It's too late to stop temperature rise. But not too late to limit it.

After more than a decade of patiently waiting and watching, astronomers have seen signs that one of the rarest stars known to science is waking up from its slumber. 

By combining math with 3D printing, researchers from Boston University have created a new material that seemingly defies logic: light and air have no trouble passing through it — but sound cannot.

When a child first does something without being asked, their parents usually celebrate. Researchers at the University of Southern California (USC) are having that moment right now.

Every once in a while, the Milky Way ejects a star. The evicted star is typically ejected from the chaotic area at the center of the galaxy, where our Super Massive Black Hole (SMBH) lives.

Do human beings have a magnetic sense? Biologists know other animals do. They think it helps creatures including bees, turtles and birds navigate through the world.

Researchers at the California Institute of Technology (Caltech) say they've found a way to levitate and propel objects using only light - though, for the time being, the work remains theoretical.

In quantum physics, particles can 'tunnel' through seemingly impenetrable barriers, even when they apparently don't have the energy to do so. Now, researchers have gleaned behind the curtain to better understand how this trick is done.

A shock discovery is in from Bennu. The NASA spacecraft analysing the asteroid has observed it shooting out plumes of dust that surround it in a dusty haze - a phenomenon we've never seen in an asteroid before.

The most sophisticated result so far.

Why do we exist? This is arguably the most profound question there is and one that may seem completely outside the scope of particle physics.

You read that right.

As we humans grow older and wiser, it's not unusual to feel as if time were whizzing by, quietly gathering speed with every year.

Jupiter's anomalous size and location in our Solar System has been puzzling researchers for years, since it doesn't fit with our understanding of planetary formation. Now, astronomers think they've figured out how the gas giant ended up in its curi

We've learned a lot about Neptune's largest moon, Triton, since it was first discovered in 1846. Some scientists believe it could be an "ocean world" with liquid water - and maybe even harbor life.
