Looking for aliens from the far side of the moon [COMIC]
Earth’s noise and light pollution can make it hard to detect signs of life on other planets. The solution? Telescopes that use the moon as a shield.

This astronomer searches for alien chemistry and tech
At the SETI Institute, Chenoa Tremblay uses radio telescopes to look for molecules and emissions given off by alien technology.

A new dwarf planet may skirt the edge of our solar system
For the distant object, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical “Planet Nine.”

Megastars shredded by black holes offer new type of cosmic explosion
Called extreme nuclear transients, these events are 30 to 1,000 times as bright as supernovas — and their glow may persist for a year or more.

A rogue black hole is on the loose in our galaxy
Astronomers now agree there’s a lone black hole wandering around the Milky Way — the first solitary black hole ever detected.

Perseverance took the first picture of a visible aurora on Mars
A faint yet visible aurora has been spotted on Mars. It’s the first such light show seen from another planet's surface.

A passing star could fling Earth out of orbit — or into the sun
Computer models show that a star's tug could send Mercury, Venus or Mars crashing into Earth — or let Jupiter eject our world from the solar system.

Scientists Say: Quasi-satellite
Unlike a true satellite, these tagalongs orbit outside a planet’s primary sphere of gravitational control.

Check out the magnetic fields around our galaxy’s central black hole
Astronomers have captured polarized light coming from the Milky Way’s supermassive black hole. This offers insight into its magnetic fields.

Explainer: What is the solar cycle?
Here’s what causes the sun’s 11-year cycle of activity and what it means for us on Earth.

Scientists Say: Corona
The sun’s corona can only be seen without special instruments during a total solar eclipse.

Forests could help detect ‘ghost particles’ from space
If trees could act as natural antennas, one physicist proposes that they just might pick up signals of hard-to-spot ultra-high energy neutrinos.
