About John Bochanski

John Bochanski is a physics professor at Rider University in Lawrenceville, NJ. John uses large surveys of the sky to study its coolest members, from nearby low-mass stars and brown dwarfs, to some of the most distant red giant stars ever discovered.

Dead Stars: Good Exoplanet Targets?

White dwarfs can have stable habitable zones for a few billion years, and planets with Earth-like atmospheres might be much easier to detect around these stellar remnants than normal, hydrogen-fusing stars.

Making Planets Around Brown Dwarfs

Astronomers searching for forming planets have a new place to look. Even the thin disks around brown dwarfs are capable of forming grains large enough that, one day, they could potentially coalesce into a rocky planet.

Oort Cloud

Making Mini-Oort Clouds

A new set of simulations shows that systems with so-called "hot Jupiters" might also have mini-Oort clouds detectable by today's space telescopes, giving astronomers a new potential tool for finding exotic extrasolar systems.

A New Goldilocks Planet

Astronomers have found a system of six super-Earths, one of which is at the "Goldilocks" distance for sustaining liquid water. The Sun-like host of the system lies only 40 light-years away.
