[Title of journal article:] Evidence for Liquid Water on the Surface of a Terrestrial Planet in the Habitable Zone

[Below the title are four lines of blurred text presumably representing the name of the author or authors and their affiliations. Below that, the text of the article is blurred, displayed in two columns. There are three sections of blurred text each with a blurred boldface heading. Two pictures are included amid the blurred text. The picture in the left column shows the sea running alongside a beach. The picture in the right column shows Jill and Kidball playing at the beach, with Jill running and Kidball building a sandcastle, while Cueball and Megan are sitting under a beach umbrella watching them.]

'A remarkable discovery': Astronomers find 1st exoplanet in multi-ring disk around star

"Discovering this planet was an amazing experience!"

Astronomers have discovered a hungry baby planet gobbling up material around an infant star located around 430 light-years from Earth. The planet has been given the suitably cute name WISPIT 2b. WISPIT 2b is estimated to be a gas giant around the size of Jupiter and around just 5 million years old. If this seems ancient, remember our solar system is around 4.6 billion years old. The extrasolar planet, or "exoplanet," is carving a channel in the planet-forming disk of gas and dust, or "protoplanetary disk," around its young parent star WISPIT 2 like a cosmic Pac-Man as it gathers material.

Did you know? Uranus is four times wider than planet Earth. And on this day in history in 1781, it was discovered by British astronomer William Herschel. He was using his telescope when he noticed an object in the sky. He thought it to be a star or comet, but within two years, other astronomers showed it was a new planet orbiting the Sun! Uranus, the third largest planet in our solar system, appears blue due to the methane in its atmosphere.

Fun fact: One Uranian year (a complete rotation around the Sun) takes about 84 Earth years to complete.

Waves on Other Planets

On Earth, most waves form when wind blows across the water. The shear and added energy from the wind ripples the surface, eventually building up waves (through the Kelvin-Helmholtz instability).  (Video, image, and research credit: U. Schneck et al.; via MIT News; submitted by Joseph S.)
