NASA/ESA Hubble Space Telescope Reveals New Image of Spiral Galaxy Messier 90.

This captivating image presents a fresh perspective of the spiral galaxy Messier 90, captured by the NASA/ESA Hubble Space Telescope.

A stunning new image of the spiral galaxy Messier 90 (M90) has been captured by the Hubble Space Telescope, showcasing the galaxy's intricate structures and star-forming regions. Located in the constellation Virgo, M90 is approximately 55 million light-years from Earth.

This latest image builds on earlier observations made with Hubble’s Wide Field and Planetary Camera 2 (WFPC2) in 1994, which displayed a distinctive stair-step pattern due to its sensor layout. In 2009, WFPC2 was replaced by the Wide Field Camera 3 (WFC3), which was used for the recent images taken in 2019 and 2023. The new data reveals M90’s dusty disk, gaseous halo, and bright core in much greater detail.

M90’s inner regions are active sites of star formation, visible in red H-alpha light from glowing nebulae. As a member of the Virgo Cluster, M90's trajectory brought it near the cluster's center around 300 million years ago. The dense gas environment exerted a strong influence on M90, stripping away vast amounts of gas and resulting in a diffuse halo. This loss of gas hampers new star formation, foreshadowing a gradual fading of the galaxy.

Interestingly, M90 is one of the few galaxies that is moving closer to Earth, as its orbit through the Virgo cluster accelerates. While many other galaxies in the cluster are moving away, M90's path is bringing it toward us. Over billions of years, it is expected to evolve into a lenticular galaxy, marking a significant transformation in its structure.

This remarkable observation underscores the dynamic nature of galaxies and their interactions within clusters, offering insights into the life cycles of these celestial bodies.

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. ...
