Sun

Get ready to see the Red Planet up close this week: , offering the closest view of the planet until 2035.

Scientists might have zeroed in on the phenomenon that heats the sun's outer atmosphere, or corona, to mind-bogglingly hot temperatures.

NASA has tapped SpaceX's Falcon 9 rocket to launch a new mission to study the protective bubble around our solar system.

We're officially nine months into solar cycle 25, scientists have confirmed, and it will likely look much like its predecessor, which ran from 2008 to 2019.

The bubble of charged particles that surrounds our solar system looks more like a deflated croissant than a comet, as traditionally envisioned, a recent study suggests.

Scientists may one day be able to predict dangerous solar flares just one day in advance using a new solar outburst model, a new study finds.

For the first time ever, physicists have spotted rare, ghostly particles, called CNO solar neutrinos, produced by a weird kind of fusion inside the sun.

New images of the solar surface, the closest ever seen, included a flaw that resembled a tardigrade.

It took just one round of photographs from a new solar science spacecraft for scientists to learn something new about the sun.

A daring sun-grazing NASA spacecraft turns its focus to Venus today (July 10) with a critical flyby that will pass through the planet's weird "tail."

It depends on whether the planet's atmosphere is predominantly filled with gas or dust particles.

This Saturday, July 4, Earth will be at the farthest point in its orbit around the sun, also known as aphelion.

NASA combined 10 years of solar observations into a single, gorgeous time-lapse video.

The sun and moon converged in a dazzling "ring of fire" solar eclipse Sunday (June 21), stunning skywatchers across parts of Africa, Asia and more.

A "ring of fire" solar eclipse, the only annular eclipse of 2020, will wow skywatchers in the Eastern Hemisphere. Here's how it works.

It's official: Summer is here for Earth's Northern Hemisphere while winter arrives in the south and Google, as always, is celebrating with artful style.

Summer will arrive in the Northern Hemisphere on Saturday (June 20) at 5:43:32 p.m. EDT (21:43:32 GMT). The June solstice also marks the beginning of winter for those in the Southern Hemisphere.

Solar Orbiter, a joint mission by NASA and the European Space Agency, has hit its first big milestone of its sun-watching mission — and the spacecraft will soon have pictures to prove it.
