Astronomy's first gap-clearing planet fills in our "missing link"
Planets grow from protostellar material in disks, leading to full-grown planetary systems in time. At last, the final gap has been filled.

A long, bumpy caterpillar-like wormhole may connect two black holes
For obvious reasons, we do not know what the inside of a black hole looks like. But thanks to theoretical physics, we can ask what the inside should look like if Einstein's theory of gravity and the r...

Why an interstellar comet has scientists excited
The comet could be older than our solar system. The comet is also distinct because nickel vapor was detected in the gas surrounding it.

In short: GJ 251 c is closer than most exoplanet targets, big enough to study in detail, and in the habitable zone. If we want to find alien life, this is one of the best shots we have right now. Exciting times ahead for exoplanet research.

Newly discovered ‘super-Earth’ offers prime target in search for alien life | Penn State University
The discovery of a possible “super-Earth” less than 20 light-years from our own planet is offering scientists new hope in the hunt for other worlds that could harbor life, according to an international team including researchers from Penn State.

That said, GJ 251 c orbits a red dwarf star—these stars are prone to flares and variable activity that could strip atmospheres or make life less likely. So while the discovery is thrilling, habitability is far from confirmed.

The planet orbits at just the right distance where liquid water could exist—provided it has an atmosphere. While we cannot yet probe that atmosphere, the team argues this candidate offers one of the best chances in the next 5-10 years to search for life elsewhere.

GJ 251 c’s location makes it a high-priority target for future observatories. Using the HPF spectrograph at the Hobby-Eberly Telescope, scientists amassed >20 years of data capturing the host star’s “wobble” to identify this planet’s presence.

Astronomers have found a “super-Earth” designated GJ 251 c, orbiting a nearby dwarf star just ~18-20 light-years from Earth. The planet is nearly 4× Earth’s mass, likely rocky, and lies in the habitable “Goldilocks” zone.
