Poor Astronomy | Could TESS have already seen Planet Nine?

Can TESS find distant Solar System objects? This is an interesting question! TESS is the Transiting Exoplanet Survey Satellite, which scans the sky for starlight dips as planets pass in front of their host stars. In order to achieve this, gigantic celestial objects are constantly being looked at, so that many different things are visible, not only indications of the …

The TESS spacecraft in search of NASA's planet offers a spectacular panorama of the Milky Way

NASA's Planet Hunting Spacecraft has created a spectacular panorama of the Southern Sky showing our home galaxy, the Milky Way. The Panorama contains 208 images taken by the Transiting Exoplanet Survey Satellite (TESS) during its first year of science operations completed on 18 July. This celestial motion is a slightly broader view than usual for the mission, which is optimized …

How did this planet get there? TESS examines a planetary puzzle

An artistic representation of a hot Jupiter exoplanet. C. Carreau / ESA The planetary satellite TESS (Transiting Exoplanet Survey Satellite) of NASA has made another fascinating discovery. This time, it's on a planet it should not be, right in the middle of a zone where a planet should have been destroyed by its star. The star HD 203949 is located …

The first year of science of TESS

NASA's youngest exoplanet hunter has found more than two dozen new worlds, at least one of which could be habitable. The prospect of finding an Earth-like exoplanet has long inspired the imagination of scientists and laymen. Now, NASA's latest Planet Hunting Mission, the Transiting Exoplanet Survey Satellite (TESS), could set such a world in turmoil. Last week, nearly 300 planet …

NASA's TESS mission discovers three new worlds

This infographic shows the main features of the TOI 270 system in the southern constellation Pictor, which is about 73 light-years away. The three known planets were discovered by NASA's Transiting Exoplanet Survey Satellite through periodic starlight dips caused by each orbiting world. Insets show information about the planets, including their relative size, and how they are compared to the …

NASA's TESS exoplanet hunter has found its first planet at earth size, but you do not want to visit it – BGR

NASA's TAS Exoplanet Hunting Telescope has been in operation for less than a year, but has already made some impressive discoveries. After announcing a new "Hot Saturn" in March, NASA just revealed that TESS had found its first planet-sized planet outside of our solar system. TESS – which stands for Transiting Exoplanet Survey Satellite – is intended to detect the …

NASA's TESS spacecraft finds its first Earth-sized exoplanet

This newly identified planet is the smallest world outside our solar system discovered by TESS. The spacecraft data shows that the HD21749c orbits its star every 7.8 days, which means that orbit has a tight orbit that would result in surface temperatures of up to 800 degrees Fahrenheit. TESS has now found ten planets smaller than Neptune, and his ability …

TESS discovers its first Earth-sized planet

NASA's Transit Exoplanet Survey Satellite, TESS, has discovered its first earth-sized exoplanet. The planet called HD 21749c is the smallest world outside of our solar system that TESS has identified so far. In an article published today in the journal Astrophysical Journal Letters an MIT-led team of astronomers report that the new planet is orbiting the star HD 21749 – …
