The Transiting Exoplanet Survey Satellite (TESS) is an astrophysics Explorer-class mission between NASA and MIT. After launching in 2017, TESS will use four cameras to scan the entire sky, searching for planets outside our Solar System, known as exoplanets. The mission will monitor over 500,000 of the brightest stars in the sky, searching for dips in their brightness that would indicate a planet transiting across. TESS is predicted to find over 3,000 exoplanet candidates, ranging from gas giants to small rocky planets. About 500 of these planets are expected to be similar to Earth's size. The stars TESS monitors will be 30-100 times brighter than those observed by Kepler, making follow-up observations much easier. Using TESS data, missions like the James Webb Space Telescope can determine specific characteristics of these planets, including whether they could support life.

TESS, the Transiting Exoplanet Survey Satellite, is NASA's newest exoplanet mission. Led by MIT, TESS will find thousands of new planets orbiting nearby stars. During its two year survey, TESS will watch a wide variety of stars, looking for signs of planets ranging from Earth-size to larger than Jupiter. Each of TESS's cameras has a 16.8-megapixel sensor covering a square 24 degrees wide — large enough to contain an entire constellation. TESS has four of these cameras arranged to view a long strip of the sky called an observation sector. TESS will watch each observation sector for about 27 days before rotating to the next. It will cover the southern sky in its first year, and then begin scanning the north. TESS will study 85 percent of the sky — an area 350 times greater than what NASA's Kepler mission first observed — making TESS the first exoplanet mission to survey nearly the entire sky. Because TESS's observation sectors overlap, it will have an area near the pole under constant observation. This region is easily monitored by the James Webb Space Telescope, which allows the two missions to work together to first find, and then carefully study exoplanets.

NASA’s new planet-hunting telescope, TESS (Transiting Exoplanet Survey Satellite), just found its first Earth-sized world. Though the Earth-sized planet, and its hot sub-Neptune companion, were first observed by TESS in January 2019, it’s taken until now to confirm their status with ground-based follow-up observations. The discovery is published in The Astrophysical Journal Letters.

Ever since NASA’s Kepler Space Telescope was launched in 2009, there has an explosion in the study of the extrasolar planets. With the retirement of Kepler in 2018, it has fallen to missions like the Transiting Exoplanet Survey Satellite (TESS) to pick up where its predecessor left off. Using observations from TESS, an international team of astronomers recently discovered three exoplanets orbiting a young Sun-like star named TOI 451.

NASA’s Transiting Exoplanet Survey Telescope launched back in April, 2018. After a few months of testing, it was ready to begin mapping the southern sky, searching for planets orbiting stars relatively nearby. We’re just over a year into the mission now, and on July 18th, TESS has shifted its attention to the Northern Hemisphere, continuing the hunt for planets in the northern skies. As part of this shift, NASA has announced a handful of fascinating new planets turned up by TESS, including a couple of worlds in categories which have never been seen before.

ESA’s CHEOPS mission is due for launch later this year (2019), it will perform follow on observations of candidate exoplanets discovered so far, trying to narrow down their size and orbital periods. Thanks to CHEOPS, the number of confirmed exoplanets will start to catch up with the number of planetary candidates.

TESS, the Transiting Exoplanet Survey Satellite, has imaged an outburst from the comet 46P/Wirtanen. It caught the outburst in what NASA is calling the clearest images yet of a comet outburst from start to finish. A comet outburst is a significant but temporary increase in the comet’s activity, outside of the normal sunlight-driven vaporization of ices that creates a comet’s coma and tail.

The planet is called TOI 700 d and it’s about 100 light years away from Earth. It orbits TOI 700, a cool M-dwarf (red dwarf) star in the constellation Dorado. This is a key discovery for TESS, since it was designed to ferret out Earth-size planets in other solar systems.
TOI 700 d is within the star’s habitable zone, where liquid water could exist on the planet’s surface, given the right atmosphere and pressure conditions. The two innermost planets, TOI 700 b and c, are too close to the star for liquid water. Image Credit: NASA’s Goddard Space Flight Center

NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star's habitable zone, the range of distances where conditions may be just right to allow the presence of liquid water on the surface. Scientists confirmed the find, called TOI 700 d, using NASA's Spitzer Space Telescope and have modeled the planet's potential environments to help inform future observations. TOI 700 is a small, cool M dwarf star located just over 100 light-years away in the southern constellation Dorado. It's roughly 40 of the Sun's mass and size and about half its surface temperature. The star appears in 11 of the 13 sectors TESS observed during the mission's first year, and scientists caught multiple transits by its three planets. The innermost planet, called TOI 700 b, is almost exactly Earth-size, is probably rocky and completes an orbit every 10 days. The middle planet, TOI 700 c, is 2.6 times larger than Earth -- between the sizes of Earth and Neptune -- orbits every 16 days and is likely a gas-dominated world. TOI 700 d, the outermost known planet in the system and the only one in the habitable zone, measures 20 larger than Earth, orbits every 37 days and receives from its star 86% of the energy that the Sun provides to Earth. All of the planets are thought to be tidally locked to their star, which means they rotate once per orbit so that one side is constantly bathed in daylight. The Spitzer data increased scientists' confidence that TOI 700 d is a real planet and sharpened their measurements of its orbital period by 56% and its size by 38%. It also ruled out other possible astrophysical causes of the transit signal, such as the presence of a smaller, dimmer companion star in the system. While the exact conditions on TOI 700 d are unknown, scientists used current information, like the planet's size and the type of star it orbits, and modeled 20 potential environments for TOI 700 d to gauge if any version would result in surface temperatures and pressures suitable for habitability. One simulation included an ocean-covered TOI 700 d with a dense, carbon-dioxide-dominated atmosphere similar to what scientists suspect surrounded Mars when it was young. The model atmosphere contains a deep layer of clouds on the star-facing side. Another model depicts TOI 700 d as a cloudless, all-land version of modern Earth, where winds flow away from the night side of the planet and converge on the point directly facing the star.

he intern’s name is Wolf Cukier and he was a summer intern at NASA’s Goddard Space Flight Center, the agency that manages TESS. Zooniverse citizen scientists in the Planet Hunters TESS program captured variations in star brightness in TESS data and uploaded them. Cukier was examining those uploads more closely when he came across the data from TOI 1338, a binary star system about 1300 light years away in the constellation Pictor.
Researchers working with data from NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered the mission’s first circumbinary planet, a world orbiting two stars. The planet, called TOI 1338b, is around 6.9 times larger than Earth, or between the sizes of Neptune and Saturn. It lies in a system 1,300 light-years away in the constellation Pictor. The stars in the system make an eclipsing binary, which occurs when the stellar companions circle each other in our plane of view. One is about 10% more massive than our Sun, while the other is cooler, dimmer and only one-third the Sun’s mass. TOI 1338b’s transits are irregular, between every 93 and 95 days, and vary in depth and duration thanks to the orbital motion of its stars. TESS only sees the transits crossing the larger star — the transits of the smaller star are too faint to detect. Although the planet transits irregularly, its orbit is stable for at least the next 10 million years. The orbit’s angle to us, however, changes enough that the planet transit will cease after November 2023 and resume eight years later. Read more: Music: "Albatross" from Universal Production Music.

The angle of TOI 1338 b’s orbit around the stars changes over time, so after 2023, there will be an eight year gap in transits from our point of view. This gap leads astronomers to believe that there are many other circumbinary planets out there, but we have to be observing at the right time to find them.

Image: Observations from NASA’s Transiting Exoplanet Survey Satellite (TESS) have revealed new details about KELT-9b’s environment. The planet follows a close, polar orbit around a squashed star with different surface temperatures, factors that make peculiar seasons for KELT-9b. The planet’s transits begin near one of the star’s hot, bright poles and progress toward the cooler, dimmer equator. Credit: NASA’s Goddard Space Flight Center.
Image: This is Figure 2 from the paper. Caption: (Left) KELT-9 b begins its transit near the star’s hot pole and moves toward the star’s cooler equator. Our transit analysis directly measures the stellar inclination ( i ), the planet’s projected alignment (λ), and the orbital inclination (i.e., the impact parameter b). We find that KELT-9 varies in effective temperature by ∼800 K between its hot poles and cooler equator. (Right) KELT-9 b’s phase-folded primary transit from TESS. The transit depth steadily decreases throughout the eclipse, indicating that KELT-9 b begins its transit near one of the host star’s hotter poles and moves toward the dimmer stellar equator.

NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered a world between the sizes of Mars and Earth orbiting a bright, cool, nearby star. The planet, called L 98-59b, marks the smallest found by TESS yet. Two other worlds orbit the same star. While all three planets' sizes are known, further study with other telescopes will be needed to determine if they have atmospheres and, if so, which gases are present. The L 98-59 worlds nearly double the number of small exoplanets -- that is, planets beyond our solar system -- that have the best potential for this kind of follow-up. L 98-59b is around 80 Earth's size and about 10 smaller than the previous record holder discovered by TESS. Its host star, L 98-59, is an M dwarf about one-third the mass of the Sun and lies about 35 light-years away in the southern constellation Volans. While L 98-59b is a record for TESS, even smaller planets have been discovered in data collected by NASA's Kepler satellite, including Kepler-37b, which is only 20 larger than the Moon. The two other worlds in the system, L 98-59c and L 98-59d, are respectively around 1.4 and 1.6 times Earth's size. All three were discovered by TESS using transits, periodic dips in the star's brightness caused when each planet passes in front of it.
