Look! Up in the sky! Is it a planet? Nope, just a star
Among thousands of known exoplanets, MIT astronomers flag three that are actually stars.

The planet’s night side likely hosts iron clouds, titanium rain, and winds that dwarf Earth’s jetstream.
An accidental discovery and a love of spectroscopic perturbations leads to the solution of a 90-year-old puzzle.
A new study shows it’s theoretically possible. The hypothesis could be tested soon with proposed Venus-bound missions.
The discovery, based on an unusual event dubbed “the Cow,” may offer astronomers a new way to spot infant compact objects.
Report led by MIT scientists details a suite of privately-funded missions to hunt for life on Earth's sibling planet.
The boiling new world, which zips around its star at ultraclose range, is among the lightest exoplanets found to date.
A newly discovered “ultrahot Jupiter” has the shortest orbit of any known gas giant.
“In astrophysics, we have only this one universe which we can observe,” the physics professor says. “With a computer, we can create different universes, which we can check.”
Mergers between two neutron stars have produced more heavy elements in last 2.5 billion years than mergers between neutron stars and black holes.
Such planetary smashups are likely common in young solar systems, but they haven’t been directly observed.
The cosmic boundary, perhaps caused by a young Jupiter or an emerging wind, likely shaped the composition of infant planets.
The results provide a blueprint for finding such systems in the universe’s quieter, emptier regions.
Study offers evidence, based on gravitational waves, to show that the total area of a black hole’s event horizon can never decrease.
In a 3Q, Salvatore Vitale describes how gravitational-wave signals suggest black holes completely devoured their companion neutron stars.
