Hubble Observes Galaxy LEDA 42160 Battling intergalactic gas Pressure in Virgo Cluster.

 


This Hubble image shows dwarf galaxy, LEDA 42160.


NASA/ESA's Hubble Space Telescope recently captured a striking image of LEDA 42160, a diminutive galaxy situated approximately 52 million light-years away in the Virgo constellation. Despite its small stature, this galaxy finds itself in the midst of a cosmic struggle within the dense environment of the massive Virgo cluster of galaxies.


The image unveils LEDA 42160 as it contends with the formidable force known as ram pressure, exerted by the intergalactic gas permeating the cluster. Ram pressure, a consequence of the galaxy's motion through space, imposes significant effects on the galaxy's star formation processes.


As LEDA 42160 traverses through the Virgo cluster, the relentless pressure from surrounding gas and dust threatens to strip the galaxy of its star-forming materials. This stripping action can hinder or even halt the birth of new stars within the galaxy. Paradoxically, however, ram pressure can also compress gas within the galaxy, fostering regions of intensified star formation.


The Hubble data utilized in crafting this image forms part of a comprehensive study focusing on dwarf galaxies experiencing ram pressure stripping within expansive galaxy clusters, such as the Virgo cluster. Previous investigations have indicated that ram pressure stripping initially triggers enhanced star formation in larger galaxies. In this study, researchers sought to ascertain whether analogous phenomena occur in smaller galaxies like LEDA 42160.


Of particular note are the conspicuous bright patches adorning LEDA 42160's lower-right quadrant, possibly indicative of vigorous star-forming regions stimulated by ram pressure stripping. By scrutinizing Hubble's observations of LEDA 42160, astronomers aim to unravel the intricate processes underlying the formation of these distinctive features within this diminutive galaxy.

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.

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...

NASA's review of the flight design of the Nancy Grace Roman Space Telescope successfully confirmed.

Critical design work for the NASA Nancy Grace Roman Space Telescope has been completed, and the design analysis has also been successfully completed, indicating that all design and developmental engineering work is now complete.  The Nancy Grace Roman Space Telescope is being managed at NASA's Goddard Space Flight Center in Greenbelt, Maryland, along with NASA's Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science stream consisting of various scientists  team is involved. After an analysis of extensive hardware testing and sophisticated modeling, an independent review panel confirms that the observatory we used, said Julie McEnery, senior project scientist for the Roman Space Telescope at NASA's Goddard Space Flight Center in Greenbelt, Maryland. Ready, it will work. Julie McNairy says of the Roman Space Telescope, what we know, what it will look like, and what it is capable of doing, and now th...

A cluster of three galaxies was imaged with the help of the Hubble telescope's camera.

Using the Hubble Telescope's Advanced Camera (ACS) and Wide Field Camera 3 (WFC3), a cluster of three galaxies was imaged.  As shown in the image, the two galaxies have merged, scientists say, just as the two galaxies in the upper right appear to be interacting with each other, it is, in fact, stars.  Its long trails and the gas spreading from both of them gives the impression that these two have just collided with each other very fast.  In the lower left of the image is the bowling-ball-sized galaxy. Scientists say that the interaction between two galaxies occurs over a long time period, however, rarely will the galaxies collide with each other.  These galaxies are so close to each other in space that they form a cluster, which scientists have named NGC 7764A.  The mass between these galaxies has caused the formation of a shape at the end that, from the point of view of our solar system, resembles the starship known as the USS Enterprise from Star Trek.
