On Earth, one of the most important factors regulating our climate is the carbon cycle. This refers to the processes by which carbon compounds are sequestered by biological (photosynthesis) and geological processes and released through volcanic activity and organic processes (decay and respiration). For billions of years, this cycle has kept temperatures relatively stable on Earth and allowed for life to flourish.
For the past few centuries, human activity has tipped the scales to the point that some refer to the current geological epoch as the Anthropocene. According to a new study by an international team of researchers, human activity is also leading to a situation where tropical rainforests (a major sequester of carbon dioxide) are not only losing their ability to soak up carbon but could actually be adding to the problem in the coming years.

Rejoice! If you’ve missed your daily fix of seeing views of our rotating Earth from space, NOAA announced that its Deep Space Climate Observatory (DSCOVR) is now back in action. The deep space satellite, which produces incredible full-disk images of our Blue Marble, has been offline since June 27, 2019 because of a problem with the spacecraft’s attitude control system. But NOAA and NASA engineers developed and uploaded a software patch to restore DSCOVR’s operations.

Don’t worry. The oceans aren’t going to dry up. At least not any time soon, so no need to add it to the list of things to worry about.
But, what would our planet look like if they did? Dr. James O’Donoghue from JAXA decided to find out.

Along with all of their space-exploration, planet-hunting, and astronomy-based endeavours, NASA also keeps a very keen eye on Earth. In fact, they have 18 satellites whose job it is to look only at Earth. And those 18 advanced satellites are helping us understand Earth in unprecedented scientific detail.
And they take pretty pictures, too.

A surtseyan eruption is a volcanic eruption in shallow water. It’s named after the island Surtsey, off the coast of iceland. In 2015, a surtseyan eruption in the Tongan Archipelago created the island Hunga Tonga-Hunga Ha‘apai. Despite the odds, that island is still there almost five years later.

400 photos. 11 minutes. That’s what it took to create this time-lapse of the Earth and stars as the International Space Station over Namibia toward the Red Sea. NASA astronaut Christina Koch captured these images.

The US President has done it again.
Just when you think things can’t get any more—”unusual”— in the White House, the President has Tweeted an American spy satellite image as part of a juvenile jab at Iranian leadership. After some sleuthing, astronomers were able to figure out which satellite it came from: a (formerly) top-secret satellite called USA 224, an optical reconnaissance satellite.

As global warming ramps up, expect to see Greenland in the news a lot. That’s because its ice sheet is under threat of melting. But that’s not the only reason. The other reason is fire.

The Raikoke Volcano, dormant for a very long time, has awoken from its slumber. The volcanic island is in the Kuril Island chain, near the Kamchatka Peninsula in Russia. Unlike its more volcanically active neighbours, Raikoke has been dormant since 1924.
Thanks to astronauts on the International Space Station, we have gorgeous photos of the eruption.
