This first-ever spaceborne all-sky transit survey will identify planets of all sizes. (CNN)NASA's new planet-hunting TESS telescope has found an exoplanet three times the size of Earth only 53 light-years away. This image shows the Curiosity rover doing a test drill on a rock dubbed "Bonanza King" to see if it would be a good place to dig deeper and take a sample. Although only about half its size, both may be similar to Neptune in our solar system, with compositions dominated by gases rather than rock. Here are a few of the interesting objects and events TESS saw during its first year. When it completes the northern section in 2020, TESS will have mapped over three quarters of the sky. TESS is surveying an area in the sky that is 400 times larger than what Kepler observed, including 200,000 of the brightest nearby stars. Despite its small size, it’s brighter than most of the nearby stars we know host planets. Bright stars allow for easier followup study through ground- and space-based telescopes. Detailed information on the TESS mission: its science goals, background information on exoplanets, a glossary of terms, and more.
With TESS, it is possible to measure and study mass, size, density, and orbit of a large group of small planets, including a sample of rocky planets orbiting within the habitable zones of their host stars. TESS Completes First Year of Survey, Turns to Northern Sky.
A piping hot planet discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS) has pointed the way to additional worlds orbiting the same star, one of which is located in the star’s habitable zone. This page contains a list of extrasolar planets that have been detected by the Transiting Exoplanet Survey Satellite (TESS).

SciTechDaily: Home of the best science and technology news since 1998. Transit data are rich with information. “Kepler discovered the amazing result that, on average, every star system has a planet or planets around it,” said Padi Boyd, TESS project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “In addition to finding a diverse set of exoplanets, TESS has discovered a treasure trove of astrophysical phenomena, including thousands of violently variable stellar objects.”. The nearby exoplanet, HD 21749b, orbits a bright neighboring star in the Reticulum constellation, with a 36-day orbit and a surface temperature of 300 degrees Fahrenheit. Rafael Luque is a researcher at the Institute of Astrophysics of the Canary Islands — where several important telescopes are located. Temperatures given for TOI 270’s planets are equilibrium temperatures, (NASA’s Goddard Space Flight Center/Scott Wiessinger). The Transiting Exoplanet Survey Satellite is expected to find over 20,000 extrasolar planets, compared to the 3,800 exoplanets known when it launched. As a star moves toward us, the color of its light shifts to shorter, or bluer, wavelengths. From light-years away down to the surface, you can explore exoplanets at home. While none of the three planets are likely habitable, more planets may yet be found farther out in the star system, orbiting in more habitable orbits. Confirmation of Toasty TESS Planet Leads to Surprising Find of Promising World, TESS Completes First Year of Survey, Turns to Northern Sky, TESS Scores ‘Hat Trick' With 3 New Worlds, NASA's TESS Creates a Cosmic Vista of the Northern Sky, Search for New Worlds at Home With NASA's Planet Patrol Project, NASA Missions Spy First Possible ‘Survivor' Planet Hugging a White Dwarf Star. This is essential both in terms of understand the particular planet, and in developing methods for reading the atmospheres of exoplanets more generally.
NASA's planet counter ticks up to 4,000, then passes it by three, with 31 new discoveries. “In a way, these planets were hiding in measurements made at numerous observatories over many years,” said Rafael Luque, a doctoral student at the Institute of Astrophysics of the Canary Islands (IAC) on Tenerife, who led the discovery team. Compare and contrast worlds in the TOI 270 system with these illustrations of each planet. Pi Mensae c is about twice the size of Earth and orbits the star Pi Mensae, 60 light-years away in the Mensa constellation. "This star was already known to host a planet, called Pi Mensae b, which is about 10 times the mass of Jupiter and follows a long and very eccentric orbit," said Chelsea Huang, a Juan Carlos Torres Fellow at the MIT Kavli Institute. With a 27.4 day observing period per segment, the satellite is most sensitive to exoplanets with a periods of less than 13 days (so that at least two transits are used for discovery). NASA’s TESS Helps Find Intriguing New World. The, Of all the NASA missions, none has visited as many planets, rings and moons as the twin, Citizen scientists discover rare exoplanet, Meet TESS, the satellite that will find thousands of planets. The glow of the Milky Way — our galaxy seen edgewise — arcs across a sea of stars in a new mosaic of the southern sky produced from a year of observations by NASA’s Transiting Exoplanet Survey Satellite (TESS).
TESS Scores ‘Hat Trick' With 3 New Worlds. Taking advantage of Titan's dense atmosphere and low gravity, Dragonfly will explore dozens of locations across the icy world, sampling and measuring the compositions of Titan's organic surface materials to characterize the habitability of Titan's environment and investigate the progression of prebiotic chemistry. Example: Kepler-438b, Gas giants, large planets with low density and composed mainly of hydrogen and helium, similar to Jupiter or Saturn in our solar system. Consider this your invitation to explore them! Facebook co-founder Mark Zuckerberg also sits on the mission's board of directors.
