Hubble Space Telescope discovers three colliding galaxies!

Hubble Space Telescope discovers three colliding galaxies!

Someday, the three galaxies in the constellation Boötes will combine into a single, enormous, brilliant galaxy. The Hubble Space Telescope has captured an incredible new image of galaxies collision course. It is rare for three galaxies to collide simultaneously, but this event is particularly notable for a different reason. All three galaxies which collide are actively generating new stars at the time of the event.

The Galaxies collision in the Boötes constellation results in one massive galaxy. At the same time, the gravitational interactions between the three galaxies will destroy the spiral structure the galaxies currently display.

SDSSCGB 10189:

These three galaxies, known as SDSSCGB 10189, appear so close together in the photograph that they might be merging. Galaxies’ original shapes have been warped further by the gas and dust that connects them. There is a lot of light coming from the three galaxies.

On the scene’s left side, there is a spiral galaxy that is not involved in the collision. This galaxy appears to be calmly watching the events unfold, much like a human who is “rubbernecking” a car crash on Earth.

Only 50,000 light-years separate the three massive star-forming galaxies that makeup SDSSCGB 10189. At first glance, this distance may appear to be quite large and relatively safe from a collision, but in a cosmological context, it is actually quite close. For instance, the distance between the sun and Andromeda, the galaxy closest to the Milky Way, is more than 2.5 million light-years.

Brightest Cluster Galaxies (BCGs) are the largest and most massive galaxies in the cosmos. The Hubble Space Telescope has captured a new image as part of an investigation into the birth of these galaxies

Barycentric Galactic Group (BCG):

In gas-rich galaxies collision and merge, a barycentric galactic Group (BCG) is created. Galactic clusters are massive structures made up of hundreds or thousands of galaxies. To understand the birth histories of these clusters, scientists can study the types of cluster galaxies that make them up. The complex structure of dark matter clumps and filaments connecting individual galaxies within a cluster is the “cosmic web.”. Scientists believe that BCGs, or Brightest Cluster Galaxies, may provide valuable insights into the history of the cosmic web.

The formation of BCGs and its implications for the evolution of the cosmos over the past 13.8 billion years remain contentious topics of discussion. Many astronomers believe these enormous, brilliant galaxies arose when the universe was only approximately 19% of its present age. Nonetheless, there are many who believe BCGs are still developing and changing in the present day.

If SDSSCGB 10189 does indeed combine, the birth of a BCG would provide much-needed insight into the formation timing of these enormous, brilliant galaxies.

Hubble Captures Spectacular Tarantula Nebula Image!

Hubble Captures Spectacular Tarantula Nebula Image!

This picture taken by the NASA/ESA Hubble Space Telescope shows the Tarantula Nebula, also known as 30 Doradus. This is a massive region of ionized hydrogen gas that is forming stars. And is located 161,000 light-years away from Earth in the Large Magellanic Cloud. The region’s bright, new stars surround by turbulent clouds of gas and dust.

Hubble is familiar with the Tarantula Nebula. The star-forming region is the brightest in our galaxy. It is home to the most vibrant and massive stars known. It is an ideal laboratory for testing theories of star formation and evolution. Hubble has a wealth of images from this region. Recently, the NASA/ESA/CSA James Webb Space Telescope explored this region and discovered thousands of young stars that had never before been seen.

Two different observing proposals combined to create this new image. The first proposal aimed to examine the characteristics of dust particles in the thick clouds of darkness in this image of the Tarantula Nebula and in the space between stars. This hypothesis, dubbed Scylla by astronomers, explains how interstellar dust interacts with starlight in a variety of settings. It works in tandem with Ulysses, another Hubble program that characterizes stars. This image also contains data from an observing program that is studying star formation in early universe conditions and cataloging the stars of the Tarantula Nebula for future research with Webb.

Hubble Telescope Captured Images a Stellar Duo in Orion Nebula!

Hubble Telescope Captured Images a Stellar Duo in Orion Nebula!

NASA/ESA Hubble Space Telescope has captured an image of stars lying in the Orion Nebula. A smaller companion star is in the upper side of this image. Moreover, the luminous variable star V 372 Orionis is the point of attention in this picture. Roughly 1,450 light-years from Earth Orion Nebula is a colossal region of star formation.

What is V 372 Orionis?

V 372 Orionis or Orion Variable is a certain type of variable star. Moreover, Orion variableshubble-telescope-captured-images-a-stellar-duo-in-orion-nebula are young stars who experience some tempestuous moods and growing pains. These stars are visible to astronomers as irregular variations in luminosity. Just as V 372 Orionis, Orion Variables has also some connections with diffuse nebulae. The variable gas and dust of the Orion Nebula fill in this image.

Which Hubble instruments took this picture?

This image also overlays data from advanced Camera for Surveys and Wide Field Camera 3. Infrared and visible wavelengths were layered to show rich details of this corner of the Orion Nebula. In the form of diffraction spikes that surround the bright stars, Hubble left its slight signature on this astronomical portrait. When the starlight, interacts with the four vanes inside Hubble that support the telescope’s secondary mirror the four spikes around the brightest stars in this image form. Apart from that, NASA/ESA/CSA James Webb Space Telescope has six-pointed diffraction spikes. This is because of Webb’s hexagonal mirror segments and 3-legged support structure for the secondary mirror.

Hubble Space Telescope Captured Cosmic Treasure Trove

Hubble Space Telescope Captured Cosmic Treasure Trove

Hubble telescope recently captured an image of a host of astronomical objects scattering in the universe. Galaxies ranging from stately spirals to fuzzy ellipticals scatter across the telescope image. While a smattering of bright foreground stars is closer to home. The small galaxy UGC 7983 sketchy shape appears as a hazy cloud of light visible in the middle of the image. In the constellation Virgo, around 30 million light-years from Earth, the small dwarf irregular galaxy UGC 7983 is located. Moreover, some researchers say that it is identical to the very earliest galaxies in the universe.

A relatively nearby astronomical interloper is also visible in the picture. Across the upper left-hand side of the image a minor asteroid in our own solar system streaks. Split by small gaps the asteroid’s trail is visible as four streaks of light. The four different exposures that were merged to make up this image are represented by these light streaks. Filter modifications inside the Hubble telescope Advanced Camera for Surveys between exposures can be seen in the tiny gaps between each observation.

In order to observe every known galaxy close to the Milky Way capturing an asteroid was a fortunate side effect of a larger effort. However, Of all the Milky Way’s near galactic neighbors, Hubble had imaged roughly 75%. A group of astronomers suggested using the gaps between longer Hubble observations to capture images of the remaining 25%. To fill gaps in the Hubble telescope observing schedule and in our knowledge of nearby galaxies, the project was an elegant and efficient way.

A New Large Space Telescope is to be launched by NASA for a Space Survey

A New Large Space Telescope is to be launched by NASA for a Space Survey

After the successful launch of the James Webb Space Telescope (JSWT), NASA is not taking any breaks. NASA is nowhere near stopping, instead of that this space research organization has announced to development of a new large space telescope. 

In the 241st AAS Meeting, NASA shared James Webb Space Telescope’s (JWST) new findings and updates. This meeting was held at Washington State Convention Center, Seattle, WA from 8, January to 12, January 2023. NASA’s research team shared Webb’s findings and results in the meeting.

NASA announced to start of developing a new next-generation space telescope in the 241st meeting of the American Astronomical Society (AAS) held from 8, January to 12, January 2023. NASA’s research team briefed Webb’s findings in the meeting.

NASA has yet discovered about 13 planets in other solar systems since 2020. Even if we say that these planets are habitable we are not confident that some of those are likely habitable. That’s the reason why scientists are now counting on Habitable World Observatory.

Nancy Grace Roman Space Telescope!

The “Nancy Grace Roman Space Telescope” aim is to determine vital questions in the areas of dark energy, exoplanets, and infrared astrophysics. The short name of “Nancy Grace Roman Space Telescope” is “Roman Space Telescope”. This infrared telescope is formerly known as the Wide-Field Infrared Survey Telescope (WFIRST). This next-generation space observatory is still developing and hopefully will be launched by May 2027.

NASA seems to be following Astro2020’s recommendation. NASA started the GOMAP ( Great Observatory Technology Maturation Program ) last year. This was a program that will focus on what are “New Great Observatories”. At the 241st meeting of the AAS (American Astronomical Society), NASA’s research team announced that they will develop an infrared space telescope which will be called a Habitable Worlds Observatory (HWO).

Features of Roman Telescope!

This impressive piece of hardware will be equipped with a 2.4-meter mirror and a 300-megapixel camera offering an image capture area 100 times larger than Hubble Telescope can produce with an identical resolution. Comparing the design of the new Roman Space Telescope with the old design, we will a lot of changes. The WFIRST design which was studied in 2011-2012, features 1.3 m (4.3 ft.) 

It is made similar to the James Webb space telescope. The current design is to create a super stable telescope that will sit out at the L2 Earth-Sun LaGrange point. This is the same sun-blocking position that James Webb uses. It will also use a James Webb-style segmented mirror. Moreover, a coronagraph is also present there to block a star’s bright cores.

Before this design, current ground-based and space base telescopes were limited to detecting young exoplanets (self-luminous). This was million times lighter than their host star and located >0.3 arc seconds away. The Nancy Grace Roman Space Telescope will be capable of detecting planetary companions 10 million times fainter than their host star and located >0.3 arc seconds away. 

Thoughts of the Astrophysics Division Director on the Roman Space Telescope!

The Astrophysics Division Director in the Science Mission Directorate at NASA Headquarters in Washington, DC named Dr. Mark Clampin has said that there is more to this mission than just a single new telescope. He shared his views:

“Even though you may at first blush look at it and say,’ Well, this is an exoplanet mission,’ it is not; it is an observatory,” 

Moreover, he said: 

“People are watching how we do on Roman as an example of whether we can do a good job in the future,” Furthermore he stated. “The Roman science is important and it’s also important that we demonstrate that we can stay on track on this telescope as we put it together. That would be my highest priority.”
