Surviving Mars missions will take planning and lots of innovation
Astronauts that go to Mars will need protection from microgravity and radiation, plus mini-medical devices to diagnose problems and manage emergencies.

Scientists Say: Gravity
Gravity is a fundamental force that attracts objects with mass to other objects with mass. It decreases with distance.

2020 Physics Nobel goes for delving into black holes
Although Einstein’s general theory of relative suggested black holes might exist, this year’s winner’s helped show they actually are out there.

Strange but true: White dwarfs shrink as they gain mass
Telescope observations of thousands of these stars now confirm a decades-old theory on how their masses relate to their waistline.

Could ripples in spacetime point to wormholes?
A new calculation reveals that strange gravitational waves detected by LIGO and Virgo could see if a black hole were falling into a hypothetical tunnel in spacetime.

Milky Way’s tidal forces are shredding a nearby star cluster
The nearest star cluster is being pulled apart, due largely to the tidal forces of our galaxy, the Milky Way. Bye bye, Hyades!

Spotted: Milky Way’s giant gas bubbles in visible light
The bubbles have different colors, based on how the gas inside them moves. That could give clues to how the bubbles developed.

See the sun in dazzling detail
These images show the sun as it has never been seen before. They come from the new Daniel K. Inouye Solar Telescope.

Our sun is neighbor to a giant wave of gas
The Earth and sun sit relatively close to a newfound thread of star-forming gas. That gas is being called the Radcliffe Wave.

This ‘Sombrero’ stole a big galaxy
The Sombrero Galaxy is an odd spiral galaxy that outshines all others within 35 million light-years of Earth. Its bright, iron-rich halo suggests it consumed one or more large galaxies.

Glass beads help scientists puzzle out how baby planets grow
Researchers have mimicked the first stages of planet formation in the lab. All they needed were glass beads and a catapult.

NASA’s Parker probe spots rogue waves and magnetic islands on the sun
The Parker probe’s first data is giving scientists a look at what’s to come as the craft moves closer to the sun over the next few years.
