Satellite, meet space station. HEO Robotics, which monitors the area around Earth and observes orbiting objects with space-based sensors, captured a stunning image of the International Space Station (ISS) using one of its satellites. The two objects were moving at 3.7 miles (6 kilometers) a second relative to each other, making the orbital image all the more notable.
Astronomers have discovered an Earth-size planet orbiting an ultracool red dwarf star similar in size to Jupiter. The red dwarf, located some 55 light-years away, is 100 times less bright than the sun and exhibits half the temperature of our star. This new extrasolar planet, or exoplanet, is named SPECULOOS-3 and represents just the second time astronomers have discovered a planetary system around a red dwarf star, the first being the Trappist-1 system.

The sunspot AR3664, which is about 15 times wider than Earth, has finally rotated out of our planet's view - but not before firing off two more big solar storms. The big flares that erupted from AR3664 over the weekend were accompanied by coronal mass ejections (CMEs), outbursts that send huge clouds of solar plasma streaking through space. Because the sunspot was facing Earth at the time, those CMEs slammed into our planet, supercharging the aurorae and causing radio blackouts in some places.
The largest planetary construction site ever seen, spanning hundreds of billions of miles in size, may very well be cast in an enormous shadow that accentuates its bizarre appearance. In short, it looks like a cosmic butterfly - and, for years, it was ignored.
Astronomers have discovered a new planetary oddball beyond the solar system that is as fluffy and light as cotton candy. WASP-193 b is the second-lightest planet in the exoplanet catalog, which contains over 5,400 entries.
In most cases, we know when a volcano is going to erupt. Well, sort of. While we can't predict the precise moment an eruption will begin, volcanoes often show signs that they're "waking up." Typically, those signs come from changes in the volcano itself, as well as from changes within the topmost layers of Earth's crust. But new research, spearheaded by teams from Imperial College London and the University of Bristol, suggests we should be looking deeper -- up to 12.5 miles (20 km) underground - at different eruption cues that might help us improve our predictions.
NASA is hoping to entice space fans of all ages to learn more about the field with ambitious and successful outreach programs, and the latest edition in their "Astrobiology" series of graphic novels is fully fueled with 28 pages of informative storytelling for comics fans and future scientists of all abilities to ingest and enjoy.
Warning: Spoilers ahead for "Star Trek: Discovery" season 5, episode 8. -- After the apparent "death" of L'ak (Elias Toufexis) last week, the sense of urgency of this fifth and final season of "Star Trek: Discovery" has certainly been ramped up, but we're still willing to wager that his resurrection via Progenitor tech will be the example to prove how important that MacGuffin actually is.
