When that image comes, it will kick off the next era of exoplanet identification and analysis, opening our eyes once again to the wonders that surround us in this universe. It is due to beam the first of those images back to Earth in June. Only sensitive to giant free-floating planets. TESS's new photograph was just a warm-up run: The telescope carries four of these cameras, and when it officially comes on duty, TESS will with every image capture a glimpse of the universe 400 times the size of this postcard home. Scientists don't know how long they have before it runs out of gas, but someday soon, NASA will send the spacecraft its last instruction: to turn off the signals it beams home and float timelessly, silently through space. But Kepler has been at work since 2009, and unlike TESS, it relies on fuel to stay in action.
the first glimpses into the atmospheres of potentially habitable planets. Tantalizing evidence has been uncovered for a mysterious population of 'free-floating' planets, planets that may be alone in deep space, unbound to any host star. TESS is taking up the task that will soon be abandoned by the Kepler Space Telescope, which has singlehandedly identified 2,619 planets. NASAs Kepler mission played a key role in this revolution by performing a. Kepler telescope glimpses population of free-floating planets. From there, they can turn to more powerful telescopes still being built to perhaps eventually answer the haunting question, "is anyone out there?" The finding was also notable because it’s the first time that the Kepler Space Telescope was able to pick up on such short microlensing events, according to research published Monday in the journal. From that information alone, scientists can calculate a distant world's size and how close it is to its sun. Those images will reveal tiny changes in the brightness of that field of stars, catching the faint dimming caused when a planet passes between the telescope and its sun.

The Transiting Exoplanet Survey Satellite, nicknamed TESS, launched in April and made its way towards the Moon, which is helping it settle into an orbit it could hold for centuries.Īs it did so, the scientists who dreamed up the telescope triggered one of its cameras to blink, capturing a two-second snapshot of the sky full of stars that it will spend its lifetime photographing.
The image comes from a new instrument designed to turn those hopes into real scientific data. TESS's first photo includes more than 200,000 stars.
