Hundred of planetary candidates have been found to collect and release the NASA Satellite Exoplanet Survey Satellite (TESS), up to eight of which have been confirmed by follow-up measurements. Exoplanet is the most interesting and interesting here.NASA / MIT / TESS

It has been a decade since the launch of the NASA Kepler mission. Starting in 2009, Kepler's spacecraft watched hundreds of thousands of stars in our galaxy, each measuring the amount of light output and looking for minor changes. According to the mechanism, Kepler and its add-on mission, K2, discovered thousands of new planet Earth throughout the stars, including a large number of potentially living and potentially life-styles throughout the world.

Kepler showed us that our planet was full of galaxies, then its successive mission, TESS – the Exoplanet Survey Satellite Video – Traveling around the world around the stars. If it is a world like Earth, it will be revealed by TESS, in front of our parent star, in our visual line. For the first time, we will be sensitive to our "holy grail" backyard on the planet.

Kepler's search had an incredible effort: he sought a narrow field of vision that approached 3,000 light years away. Its main objective was to constantly see this area every year. Kepler encapsulated more than 100,000 stars, systematically and periodically searching for the total number of light in each star. Whenever it was discovered, he indicated the presence of the planet, with the magnitude and period of the planet's radius and orbital distance.

But TESS is different. Instead of looking for a narrow sky region, TESS explores the whole sky, by sector, to look for the planets around our nearest stars. If we have a serendipitously aligned planet around a 200-ray star, TESS will find it by extending its radius and orbital distance. Additionally, the discovery of TESS in our planet also gives us the chance system, where the future observatories, such as James Webb Space Telescope, can find potential signs of life.

Tess launched in April 2018, began looking for new worlds. His first scientific data began in July; About half a year later, he delivered his first release. Throughout his life, TESS hopes to find many new planets around many stars, from the giant gas giants of Jupiter to the giant and giant worlds.

With the survey in the first six sectors, TESS has highlighted what has been found so far:

  • Over 300 candidates on the planet,
  • 8 confirmed the planets,
  • including some of the giant planets,
  • and almost less than the Earth.

But the numbers are not those discoveries doing justice. By analyzing one of these findings in detail, TESS can deliver scientific phenomena to us.

The first confirmed planet was Pi Mensae c, which was very similar to our star. Just 10% more massive and 20% higher than our Sun, Pi Mensae is very similar to our star, but the solar system must be very different. By blocking a small part of its light, Pi Mensae c is very close to its star, within 6.3 days. The earth's radius doubles and is almost five times the massive heat of Earth and Neptune, which is quite typical.

But it's not typical; this is remarkable. In 2001, a large planet was discovered by Pi Mensae's orb. Pi Mensae b. It was never found among the massive planet: more than 10 times the mass of Jupiter. Its orbit is very eccentric, far beyond the Jupiter sun (5.54 UA), but its periastro passes almost in the Earth's orbit (1.21 UA).

Pi Messae, now that Tessen has found that, for the first time, we have found a distant and far-off planet, in the same system, because of the different properties and orbits. The main theories that make up close planets are virtually circular orbit, must be confused with creating an eccentric Jupiter-mass (or larger) planet.

Pi Mensae is an extreme system that we know today, and the mystery of how such systems can achieve this configuration will surely be a matter of research and speculation in the future.

Today we know more than 3,500 confirmed exoplanets, with more than 2,500 Kepler data. These planets are larger than Jupiter than smaller Earth. Due to the limits of Kepler's size and duration of the mission, most Earth-sized planets are near heat and star. TESS has the same problem in the first knowledge plans: preferably hot and near orbit.NASA / Ames Research Center / Jessie Dotson and Wendy Stenzel; Earthquakes like Earth are missing E. Siegel

The planet's extreme planet has been discovered LHS 3884bThe radius of our home world is slightly higher than the Earth 1.3 times, but its parent star makes it a revolution every 11 hours. 49 at a distant distance of clear light, the world is so hot that the star-faces load between lava cutting pools. The world, at least, in theory, it's hot that rock gets into the liquid phase.

Although it may be difficult to have mass and temperature properties in the atmosphere, always create a thin one, depending on its chemical composition or near the surface of the planet. The characteristics of this system make it an ideal candidate for measuring the spectrum of atmospheric absorption. If there is one, we will know what we have done to find out when we have the right telescope.

The planetary candidate on the HD 21749 is perhaps the most interesting find out of TESS, and it shows us the solar system among all those we have ever encountered.NASA / MIT / TESS

Most visible, TESS has given us a nearby star to keep an eye on it: HD 21749. 53 is light-only, this star is smaller and smaller than Sun: 70% large and large. As a star of the K-class, the planets should not be orbited; they should close the catastrophic disaster or tide; If the Earth's sized world is the right distance from that star, the world of life would be a great opportunity.

New Year's Eve, TESS group posted a paper This star announces the discovery of a planet that orbits: HD 21749b, 36-day orbit, and 2.84 times Earth's radius. This world was somewhat lower than Neptune, who confirmed the observation of observation, which confirmed that the mass was 23.2 times mass of ground, because it was smaller than Uranus or Neptune, but massive and nuclear.

In the first three months of public data in the TESS mission of NASA, MIT and elsewhere scientists have confirmed a new planet, HD 21749b – The third small planet has been found by TESS. HD 21749b stars a star around the sun's size, 53 light-years.NASA / MIT / TESS

This is interesting for several reasons. First of all, in distances, the temperature must be hot, but not cold: around 300 ° F (150 ° C). Secondly, it is the longest known exoplaneta known within 100 light years of Earth. And, perhaps, the most interesting ones, there is a hint of the signal – and possible planet-candidate – to get the star HD 21749 system. The supplementary candidate, if confirmed, would be an 8-day period and a land-scale radius.

If the planet exists, it would be the first earth in the world detected by TESS: the smallest discovered by this new observatory.

The ultimate goal of TESS Earth and worlds like Earth is a star system that can potentially live the world. Because TESS is optimized for leaving our nearest stars, one of the future targets will be the strongest observatory of the future, but those that are not capable of perceiving them, but which measure atmospheric content. If we were lucky, some of these worlds can find molecules like water, methane, carbon dioxide or even oxygen.

These worlds will not be the slam dunes, but TESS takes a step closer to the nearest world, to have the greatest hope of finding out beyond our Solar System. The world we have found so far is very fascinating, and a few months to enter the first mission, TESS will easily find the best forecasts. As James Webb Space Telescope has set up, TESS should give it to other parts of the world, to make our next hunger an ideal place to reach our final goal: to find a living world.
