Bending Spacetime Reveals New Planet Hidden in Archived TESS Data
NASA’s Transiting Exoplanet Survey Satellite (TESS) has captured evidence of a Jupiter-like world orbiting another star, using a trick straight out of Einstein’s relativity: gravitational microlensing. The technique marks a first for TESS, and opens up the possibility of a whole new category of planets the spacecraft might uncover.
Mallory Harris was scrolling through eight years of data collected by the TESS telescope when she came across a brightness curve that shouldn't have been there. It wasn't a transit, or the familiar signature of a planet obscuring its star for a few hours. It was something rarer: the signature of a gravitational microlensing event, that is, light bent by spacetime from another star, at distances NASA's telescope was never designed to measure. Har…
Telescope Uses Ripples in Space-Time to Detect a Huge Planet for the First Time
No matter if you’re into news about alien planets being discovered or not, you’ll probably have to get used to hearing a lot about that in the near future. That’s because our species will soon launch the mother of all planet-hunting space telescopes, the Nancy Grace Roman, tasked with unveiling 100,000 alien worlds. But before that one gets here, the TESS is not too bad at its job either. TESS is an acronym ... (continue reading...)
NASA's Transiting Exoplanet Survey Satellite (TESS) has identified a new planet, named Gaia23bra b, using gravitational microlensing. This discovery represents a significant advance in the search for exoplanets, expanding the possibilities of detecting distant worlds. Discovery of Gaia23bra b: Gaia23bra b is a super-Jupiter type exoplanet, orbiting an orange dwarf star at a distance similar to that of Jupiter from the Sun. The planet was found i…
TESS just found a planet in a new way—and more may be hiding in its eight years of data
For the first time, NASA’s TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to its warping of space-time. Unlike the star-hugging transiting planets TESS regularly reveals, the newfound microlensing world is a super-Jupiter orbiting far from its host star. “When TESS launched, no one expected it to ever […] The post TESS just found a planet in a new way—and more may be hiding in its eigh…
