TRAPPIST-1 planets provide clues to the nature of habitable worlds
New software, called ExoPlex, allowed researchers to combine all of the available information about the TRAPPIST-1 system, including the chemical makeup of the star, rather than being limited to just the mass and radius of individual planets.

New data from the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes have been used to create this stunning image showing a web of filaments in the Orion Nebula. These features appear red-hot and fiery in this dramatic picture, but in reality are so cold that astronomers must use telescopes like ALMA to observe them.

With NASA's Juno spacecraft, scientists have gotten a good look at the top and bottom of the planet for the first time. What they found astounded them: bizarre geometric arrangements of storms, each arrayed around one cyclone over the north and south poles - unlike any storm formation seen in the universe.
