Planetary science and exploration

A set of flight camera electronics on one of the TESS cameras, developed by the MIT Kavli Institute for Astrophysics and Space Research (MKI), will transmit exoplanet data from the camera to a computer aboard the spacecraft that will process it before transmitting it back to scientists on Earth.

TESS readies for takeoff

Satellite developed by MIT aims to discover thousands of nearby exoplanets, including at least 50 Earth-sized ones.

Researchers at MIT and the Australian National University have found that seismic waves are essentially blind to a very common substance found throughout the Earth's interior: water.

Scientists find seismic imaging is blind to water

Findings may lead scientists to reinterpret seismic maps of the Earth's interior.

Five new planets have been discovered outside our solar system, all orbiting a sun-like star located within the constellation Aquarius, nearly 620 light years from Earth. The alien worlds are considered super-Earths, sizing in at two to three times larger than our own blue planet.

Magnetic reconnection is a complicated phenomenon that Nuno Loureiro, an associate professor of nuclear science and engineering and of physics at MIT, has been studying in detail for more than a decade. To explain the process, he gives a well-studied example: “If you watch a video of a solar flare” as it arches outward and then collapses back onto the sun’s surface, “that’s magnetic reco...

This artist’s impression shows the view from the surface of one of the planets in the TRAPPIST-1 system. At least seven planets orbit this ultracool dwarf star 40 light-years from Earth and they are all roughly the same size as the Earth. Several of the planets are at the right distances from their star for liquid water to exist on the surfaces.

Neighboring exoplanets may hold water, study finds

Observations and modeling suggest TRAPPIST-1 exoplanets may have held onto water, billions of years after their formation.

New measurements of lunar rocks have demonstrated that the ancient moon generated a dynamo magnetic field in its liquid metallic core (innermost red shell). The results raise the possibility of two different mechanisms — one that may have driven an earlier, much stronger dynamo, and a second that kept the moon’s core simmering at a much slower boil toward the end of its lifetime.

Lunar dynamo’s lifetime extended by at least 1 billion years

Findings suggest two mechanisms may have powered the moon’s ancient churning, molten core.

For the first time, astronomers have observed a star pulsing in response to its orbiting planet. The star, HAT-P-2, pictured, is one of the most massive exoplanets known today. The planet, named HAT-P-2b, tracks its star in a highly eccentric orbit, flying extremely close to and around the star, then hurtling far out before eventually circling back around.

Scientists observe first planet-induced stellar pulsations.

“There seems to be no shortage of exoplanets,” says Jennifer Burt, a Torres postdoctoral fellow in MIT’s Kavli Institute for Astrophysics and Space Research. “There are a ton of them out there, and a ton of science to be done.”
