Exoplanets come in a variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big as Earth. They can orbit their stars so tightly that a “year” lasts only a few days; they can orbit two suns at once. Each is an entire world. https://exoplanets.nasa.gov/what-is-an-exoplanet/planet-types/overview/

Overview | Planet Types – Exoplanet Exploration: Planets Beyond our Solar System

So far scientists have categorized exoplanets into the following types: Gas giant, Neptunian, super-Earth and terrestrial, but there is complexity within these groups.

800 million light-years away, in the Pegasus constellation, @NASAHubble captured this image of a galaxy floating in space. Tendrils of star-forming gas dangle from the galaxy, seen edge-on. Astronomers gave it a nickname, but what do you see? https://go.nasa.gov/3M2ahKH

Hubble Snaps a Galactic Jellyfish

Streams of star-forming gas dripping from the disk of galaxy JW100 are formed by a process called ram pressure stripping.

Seven Earth-sized worlds orbit the TRAPPIST-1 star, ~40 light-years away. @NASAWebb studied the innermost planet and measured its temperature and found little evidence of an atmosphere. These observations bode well for studying the rest of the planets: https://go.nasa.gov/42VAWiu

Webb Measures the Temperature of a TRAPPIST-1 Exoplanet

An international team of researchers has used NASA’s James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b.
Exoplanet Exploration: Planets Beyond our Solar System
#NASAExoplanets

Scientists made models for TRAPPIST-1 b: with an atmosphere and without. @NASAWebb's measurements matched the model for a planet without atmosphere. This bodes well for Webb's ability to study temperate, Earth-size planets, like other TRAPPIST-1 worlds. https://go.nasa.gov/42VAWiu

#NASAExoplanets

Our first look at a TRAPPIST-1 planet with @NASAWebb reveals the innermost world’s dayside temperature of about 450 degrees F (232 C) and suggests it has no significant atmosphere. It's the first direct measurement of *any* light from a rocky exoplanet. https://go.nasa.gov/42VAWiu

At first glance, this image may appear to be a view of stars. Rather, almost all these different colored dots are black holes or entire galaxies. When we add sound, we can hear the data. Music represents the full range of X-ray frequencies collected by @chandraxray.

The central region of this image contains an incredible concentration of supermassive black holes, equivalent to about 5,000 objects that would fit into the area on the sky covered by the full Moon.

Small stars, giant planets?

#NASAExoplanets

Small stars may host bigger planets than previously thought

Stars with less than half the mass of our Sun are able to host giant Jupiter-style planets, in conflict with the most widely accepted theory of how such planets form, according to a new study led by UCL and University of Warwick researchers.

Depending on your hemisphere, it's the first day of spring … or fall. Either way, yay! Many exoplanets not only may not have seasons, they may be tidally locked, so the same side always faces the star, like the Moon to Earth. It's always everlasting day or never-ending night.
