Hubble Captures Stunning Image of Supernova in Galaxy LEDA 857074.

NASA and ESA's Hubble Space Telescope has provided a remarkable view of the galaxy LEDA 857074, located in the constellation Eridanus. This barred spiral galaxy, notable for its partially broken spiral arms, has recently been in the spotlight due to the supernova SN 2022ADQZ, which is brightly illuminating the right side of the galaxy’s bar.

Supernova SN 2022ADQZ is the result of a massive star's explosive end. As such a star exhausts its hydrogen fuel, it fuses heavier elements, leading to a decrease in the outward radiation pressure that counteracts gravitational collapse. This core collapse triggers a supernova explosion, with the remnant core potentially becoming a neutron star or collapsing further into a black hole.

Detected by an automated survey in late 2022, SN 2022ADQZ prompted astronomers to observe its host galaxy with Hubble in early 2023. Hubble's advanced optics allow it to separate the supernova's light from that of its host galaxy, providing detailed measurements that are often challenging for ground-based telescopes to achieve.

While thousands of supernovae are discovered annually, identifying one in any given galaxy among the millions cataloged is rare. The observation of SN 2022ADQZ has allowed LEDA 857074 to join the ranks of celestial objects captured in Hubble’s extensive archive, highlighting the significance of this cosmic event.

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. ...
