Researchers have discovered a "super-Earth, in which there is a possibility of life.

The constellation of Eridanus, 105 light-years away from the Solar System, contains a high proper speed red dwarf star known as LP 890-9, which has a mass of 12% and 15% of the Sun's radius, and a temperature At 2,871 K (2,598 °C; 4,708 °F), it is the second coldest star to host a planetary system after TRAPPIST-1. Researchers discovered LP 890-9b using the Transiting Exoplanet Survey Satellite (TESS), and LP 890-9c was discovered during follow-up observations of LP 890-9b, Both these planets fall in the super-Earth category.

The researchers found that the two planets are comparatively quiet, and are orbiting the red-dwarf star, LP 890-9, an inner planet that is about 30% larger than Earth, With an estimated temperature of 253 °F (123 °C), it is too hot for human life, but LP 890-9c is an outer planet, it is colder at an estimated 30 Fahrenheit (minus 1.1 Celsius), and remains close to its star. LP 890-9c orbits within the habitable zone of its star, LP 890-9c is a favorable target for atmospheric characterization, researchers have discovered the planet through a ground-based telescope survey, Eclipse of Ultra-cool Stars.

The actual temperature of these two planets depends on their atmospheres, but nothing is known about them, LP 890-9c's atmosphere has given rise to the greenhouse effect, which could be similar to that of Venus in the future. These two planets orbit their stars tightly, where a year on planet LP 890-9 b is only 2.7 days, while a year on planet LP 890-9 c is 8.5 days.

LP 890-9 is a much smaller and cooler star than our Sun, and the planet LP 890-9c is orbiting closely within the star's habitable zone, and researchers have added this new planet to the world's discovery list. LP 890-9c may be investigated in the future by the James Webb Space Telescope, webb has begun to study the gases present in the exoplanet's atmosphere, the webb telescope's instruments include spectrographs, which can be used to observe the exoplanet's atmosphere.

In the triple-star system, KOI-5Ab is seen orbiting the primary star...

KOI-5Ab continues to be a topic of discussion for researchers, as koi-5Ab has been seen orbiting the primary Star, confirming it has also been announced. koi-5ab revolves around the primary star, it was thought to be a planet half the size of Saturn in a planetary system, and was the only other planet candidate to be detected by the KOI-5Ab mission. Kepler mission operations were initiated by NASA in 2009, by the end of spacecraft operations in 2018, the Kepler spacecraft had discovered 2,394 exoplanets, or planets orbiting stars beyond our sun, and about 2,366 exoplanets such There are also those, which are still to be confirmed. David Ciardi, chief scientist at NASA's Exoplanet Science Institute, says the KOI-5AB was abandoned, because it was complicated, and we had thousands of candidates, and we were learning something new every day from Kepler, so that the KOI Mostly forgot to -5. KOI-5Ab is part of the Triple Star system, where KOI-5 is a group of three st...

NASA's Spitzer Space Telescope will be closed.

NASA briefly informed that the Spitzer Space Telescope will be permanently discontinued on January 30, 2020. After about 16 years of discovering the universe in light energy. And by that time, the space shuttle has been working for more than 11 years beyond its prime mission, Spitzer examines the universe's various objects in infrared light. It was in 2003 through the rocket that the American Space Research Organization NASA entered the space and entered the orbit around the Earth. Spitzer rotates the sun on a path similar to that of the Earth but it runs a bit slower. Today it is about 158 million miles (254 million kilometers) away from our planet - more than 600 times the distance between Earth and Moon. The spacing of Spitzer's orbit curve means that when the spacecraft indicates its fixed antenna on the earth to download data or receive commands, its solar panels tend to lean away from the sun. During those periods, to operate the space shut...

SpaceX is launching its next dragon spacecraft.

SpaceX is preparing for its next mission, very soon Spacex will launch the Dragon Spacecraft with its Falcon 9 Rocket. SpaceX is the 18th commercial reproduction service mission, dragon spacecraft will be loaded with dozens of experiments made in space. Launch date: Sunday, July 21, 2019 at 7:35 pm International Space Station (ISS) us The National Laboratory SpaceX's dragon is giving a finalization to more than two dozen payloads for launch in a circular circular laboratory. Many of these payloads are aimed at improving human health on the earth, many of which are focused on drug development. In addition, a series of payloads from identified private sector partners will be launched on this mission. More than 40 student experiments and demonstrations have been included on the 18th Commercial Recepti Services Mission (CRS-18) of SpaceX. One part of ISS American National Laboratory's goal is to encourage and engage next generation scientists. ...
