Topic: TESS
According to new research using data from NASA’s retired planet-hunting mission, the Kepler space telescope, about half the stars similar in temperature to our Sun could have a rocky planet capable of supporting liquid water on its surface. ![]() This illustration depicts Kepler-186f, the first validated Earth-size planet to orbit a distant star in the habitable zone.

NASA’s TESS Satellite images used to create Northern Sky Panorama
TESS locates planets by simultaneously monitoring many stars over large regions of the sky and watching for tiny changes in their brightness. When a planet passes in front of its host star from our perspective, it blocks some of the star’s light, causing it to temporarily dim. ![]() This detail of the TESS northern panorama features a region in the constellation Cygnus. At center, the sprawling dark nebula Le Gentil 3, a vast cloud of interstellar dust, obscures the light of more distant stars. A prominent tendril extending to the lower left points toward the bright North America Nebula, glowing gas so named for its resemblance to the continent.

NASA’s TESS Satellite, Spitzer Space Telescope find Large World Orbiting Young Star
The system, known as AU Mic for short, provides a one-of-kind laboratory for studying how planets and their atmospheres form, evolve and interact with their stars. ![]() This image is an artist’s concept of the planet AU Mic b and its young parent star. The faint band of light encircling the pair is a disk of gas and dust from which both the star and the planet formed.

NASA says Young Giant Planets could help answer questions on how Planets Form
Among the most intriguing of these distant worlds is a class of exoplanets called hot Jupiters. Similar in size to Jupiter, these gas-dominated planets orbit extremely close to their parent stars, circling them in as few as 18 hours. ![]() This image shows a type of gas giant planet known as a hot Jupiter that orbits very close to its star. Finding more of these youthful planets could help astronomers understand how they formed and if they migrate from cooler climes during their lifetimes.

NASA says NESSI Emerges as New Tool for Exoplanet Atmospheres
Since February 2018, scientists have been testing an instrument at the Hale Telescope called the New Mexico Exoplanet Spectroscopic Survey Instrument, or NESSI. ![]() The Hale Telescope is located on Palomar Mountain in San Diego County, California.

NASA’s Transiting Exoplanet Survey Satellite (TESS) discovers Earth size planet within Habitable Zone
TOI 700 d is one of only a few Earth-size planets discovered in a star’s habitable zone so far. Others include several planets in the TRAPPIST-1 system and other worlds discovered by NASA’s Kepler Space Telescope. ![]() TOI 700, a planetary system 100 light-years away in the constellation Dorado, is home to TOI 700 d, the first Earth-size habitable-zone planet discovered by NASA’s Transiting Exoplanet Survey Satellite.

NASA’s Spitzer Space Telescope observes conditions on Rocky Planet
The planet likely has little to no atmosphere and could be covered in the same cooled volcanic material found in the dark areas of the Moon’s surface, called mare. ![]() This artist’s illustration depicts the exoplanet LHS 3844b, which is 1.3 times the mass of Earth and orbits an M dwarf star. The planet’s surface may be covered mostly in dark lava rock, with no apparent atmosphere, according to observations by NASA’s Spitzer Space Telescope. (NASA/JPL-Caltech/R.

NASA’s TESS Satellite discovers Hot Planet, Leads to finding more Worlds
The new worlds orbit a star named GJ 357, an M-type dwarf about one-third the Sun’s mass and size and about 40% cooler that our star. The system is located 31 light-years away in the constellation Hydra. In February, TESS cameras caught the star dimming slightly every 3.9 days, revealing the presence of a transiting exoplanet — a world beyond our solar system — that passes across the face of its star during every orbit and briefly dims the star’s light. ![]() This diagram shows the layout of the GJ 357 system. Planet d orbits within the star’s so-called habitable zone, the orbital region where liquid water can exist on a rocky planet’s surface. If it has a dense atmosphere, which will take future studies to determine, GJ 357 d could be warm enough to permit the presence of liquid water.

Small Planet discovered by NASA’s Transiting Exoplanet Survey Satellite
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. «Read the rest of this article» Sections: Technology | No Comments
NASA’s TESS Satellite discovers its first ExoplanetsNASA’s Goddard Space Flight Center
The mission’s sensitive cameras also captured 100 short-lived changes — most of them likely stellar outbursts — in the same region of the sky. They include six supernova explosions whose brightening light was recorded by TESS even before the outbursts were discovered by ground-based telescopes. ![]() NASA’s Transiting Exoplanet Survey Satellite (TESS) has found three confirmed exoplanets in the data from the space telescope’s four cameras.
