59 New Planets Discovered in Our Neighborhood
The CARMENESE Consortium just released the first collection of data, which revealed 59 new exoplanets and doubled the number of known planets around Red Dwarf suns.
Machine Learning is a Powerful Tool When Searching for Exoplanets
A new machine learning technique will help astronomers detect young exoplanets in disks surrounding other stars.
Hubble and Spitzer Team up to Find a Pair of Waterworld Exoplanets
Using data from Hubble and Spitzer, an international team has discovered two new waterworlds in one system.
Are Planets Tidally Locked to Red Dwarfs Habitable? It’s Complicated
Astronomers are keenly interested in red dwarfs and the planets that orbit them. Up to 85% of the stars in the Milky Way could be red dwarfs, and 40% of them might host Earth-like exoplanets in their habitable zones, according to some research. But there are some problems with their potential habitability. One of those …

Do Exoplanet Scientists Have Favorite Exoplanets?
Exoplanets have become quite the sensation over the last decade-plus, with scientists confirming new exoplanets on a regular basis thanks to NASA’s Kepler and TESS missions, along with the James Webb Space Telescope recently examining exoplanet atmospheres, as well. It’s because of these discoveries that exoplanet science has turned into an exciting field of intrigue …

A White Dwarf is Surrounded by Torn-up Pieces of its Inner Planets and its Kuiper Belt
What will happen to our Sun? In several billion years, it’ll cease fusion, shrivel into a white dwarf, and emanate only remnant heat. There it’ll sit, dormant and comatose. But the Sun anchors the entire Solar System. What will happen to Earth? To the rest of the planets? To the rest of the objects in …
Keck's new Planet Hunter Instrument Comes Online, Searching for Smaller, More Earth-Sized Exoplanets
There’s a new planet hunter in town, and it’s got its sights set on nearby Earth-sized planets in the galactic neighborhood.
The Case of the “Missing Exoplanets”
A team of astronomers with the CLEVER Planets project have developed a model that may explain the mystery of the “missing exoplanets.”
Webb Can Detect Planets Orbiting White Dwarfs, And Maybe Even See Signs of Life
In a recent study accepted to the Monthly Notices of the Royal Astronomical Society, an international team of researchers led by Texas A&M University investigate how the James Webb Space Telescope (JWST) can detect a variety of exoplanets orbiting the nearest 15 white dwarfs to Earth using its Mid-Infrared Instrument (MIRI) Medium Resolution Spectrograph (MRS). …

Two “Super Mercury” Exoplanets Found in a Single System
There’s a star system out there with three super-Earth planets and two super-Mercuries. Super-Earths are fairly familiar types of exoplanets, but super-Mercuries are rare. Those are planets with the same composition as our own Mercury, but larger and denser. Yet, here’s HD 23472, showing off two of eight known super-Mercuries in the galaxy.
