MIT scientists develop low-cost, high-precision fabrication method for thin mirrors and silicon wafers

Technologies that depend on lightweight, high-precision optical systems, like space telescopes, X-ray mirrors, and display panels, have developed significantly over the past several decades, but more advanced progress has been limited by seemingly simple challenges. For example, the surfaces of mirrors and plates with microstructures that are necessary in these optical systems can be distorted […]

MIT welcomes two from the Heising-Simons Foundation 51 Pegasi b Fellowship for 2022

MIT’s School of Science welcomes postdocs Malena Rice and Eva Scheller, recipients of the 2022 51 Pegasi b Fellowship. The announcement was made March 31 by the Heising-Simons Foundation. The 51 Pegasi b Fellowship, named after the first exoplanet discovered orbiting a sun-like star, was established in 2017 to provide postdocs with the opportunity to […]

Scientists develop the largest, most detailed model of the early universe to date

It all started around 13.8 billion years ago with a big, cosmological “bang” that brought the universe suddenly and spectacularly into existence. Shortly after, the infant universe cooled dramatically and went completely dark. Then, within a couple hundred million years after the Big Bang, the universe woke up, as gravity gathered matter into the first […]

Look! Up in the sky! Is it a planet? Nope, just a star

The first worlds beyond our solar system were discovered three decades ago. Since then, close to 5,000 exoplanets have been confirmed in our galaxy. Astronomers have detected another 5,000 planetary candidates — objects that might be planets but have yet to be confirmed. Now, the list of planets has shrunk by at least three. In […]

A “hot Jupiter’s” dark side is revealed in detail for first time

MIT astronomers have obtained the clearest view yet of the perpetual dark side of an exoplanet that is “tidally locked” to its star. Their observations, combined with measurements of the planet’s permanent day side, provide the first detailed view of an exoplanet’s global atmosphere. “We’re now moving beyond taking isolated snapshots of specific regions of […]
