Hubble Telescope views a galactic supernova site.

In this image the spotlight falls on the diminutive galaxy UGC 5189A, positioned approximately 150 million light-years distant within the Leo constellation. The NASA/ESA Hubble Space Telescope turned its gaze toward this cosmic neighbor to scrutinize the aftermath of a spectacular supernova, specifically the explosive event known as SN 2010jl, which unfolded in 2010.What sets this supernova apart is its extraordinary luminosity, outshining our Sun by a staggering 2.5 billion times in visible energy over a remarkable three-year span. The sheer brilliance of SN 2010jl stands as a celestial spectacle, offering astronomers valuable insights into the dynamics of these cosmic explosions.

The allure of studying the aftermath of supernovae extends beyond their visible lifespans, offering a window into the intriguing realms where these cosmic explosions transpired. Even as their luminosity wanes, delving into the environments that hosted these supernovae becomes a key avenue for astronomers. Such investigations yield valuable insights, enhancing comprehension of the diverse triggers behind supernova occurrences. Supernova's studies play a pivotal role in unraveling the immediate consequences of these events – from their profound impact on surrounding gas and dust to the enduring stellar remnants they leave in their wake. In essence, each exploration into these cosmic aftermaths contributes to a deeper understanding of the intricate tapestry of celestial phenomena.

The image presented here stems from data amassed in three of Hubble's most recent studies dedicated to unraveling the mysteries of UGC 5189A.These comprehensive investigations not only delve galaxy but also cast their lens on other neighboring galaxies that have played host to recent supernovae. In astronomical terms, the term "relatively nearby" takes on cosmic proportions, indicating galaxies positioned approximately 100 million light-years away. Through this ongoing scrutiny, astronomers glean a more nuanced understanding of the dynamic processes shaping these distant cosmic landscapes.

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. ...
