Shakti and Shiva: Ancient Star Duos in Milky Way Galaxy’s Tale of Creation

[ad_1] Scientists have recently uncovered two ancient streams of stars within the Milky Way Galaxy, dubbed Shakti and Shiva, shedding light on the galaxy's earliest formation stages. These star structures, identified using data from the Gaia space telescope, are believed to have merged with the Milky Way around 12 billion years ago, providing vital clues about its early evolution.Named after Hindu deities, Shakti and Shiva consist of stars with similar chemical compositions, suggesting they formed roughly 12-13 billion years ago. Each structure boasts a mass about 10 million times greater than the sun, underscoring their significance in the galaxy's formative years. This discovery marks a crucial milestone in understanding the galaxy's turbulent infancy. Lead researcher Khyati Malhan fr...

What is Square Kilometre Array, the world’s largest radio telescope and India’s critical role in it

[ad_1] India is increasingly and rapidly stepping up its game in space missions and discoveries. With a number of new upcoming missions planned by the space agency, the Indian Space Research Organisation (ISRO), India has also laid out its investment plans for a monetary contribution to the international astronomical collaboration project, which includes over 16 nations. The collaboration between the nations will be developing the world's largest radio telescope called the Square Kilometre Array (SKA), which will be responsible for studying galaxies present in the universe. Additionally, it aims to make available the data as to evolution of our galaxy. Know what the project is about and how and when it will be ready to conduct research.About Square Kilometre Array (SKA)According to a re...

GUSTO telescope to launch on a balloon! This NASA mission will map space between stars in Milky Way Galaxy

[ad_1] NASA never fails to amaze with its groundbreaking projects. Currently, NASA scientists and Engineers are gearing up for an extraordinary NASA experiment named GUSTO (Galactic/Extragalactic ULDB Spectroscopic Terahertz Observatory) in Antarctica. According to NASA, this innovative project involves a balloon-borne telescope set to launch "no earlier than December 21” as per NASA. Yes, you read that right, it is a balloon-borne telescope. While it will be no match for the James Webb Space Telescope, It will still be a big cog in the gargantuan NASA machine consisting of land, air and space telescopes. It will launch from the Ross Ice Shelf, near the U.S. National Science Foundation's McMurdo Station research base.Mapping the Milky Way with GUSTOAs explained by NASA, GUSTO's primary ...

Historic! ALMA telescope finds first-ever planet-forming disk beyond the Milky Way Galaxy

[ad_1] A groundbreaking discovery has been made by astronomers who identified a swirling disk of material, akin to those surrounding infant stars in the Milky Way Galaxy feeding a young star situated in the Large Magellanic Cloud, a neighboring galaxy located 160,000 light-years away. Using the Atacama Large Millimeter/submillimeter Array (ALMA), the largest Earth-based astronomical project comprising 66 antennas in Northern Chile, the research team led by Durham University scientist Anna McLeod observed the system designated HH 1177 within a massive gas cloud. This marks the first confirmed extragalactic accretion disk ever detected.First Glimpse of an Extragalactic Accretion Disk"When I first saw evidence for a rotating structure in the ALMA data, I could not believe that we had detec...

James Webb Space Telescope takes captivating image of Galaxy NGC 6822

[ad_1] The European Space Agency has released a stunning picture of the Galaxy NGC 6822. This galaxy is known to be nearest to the Milky Way Galaxy. It was captured with the efforts of the Near-InfraRed Camera (NIRCam) and Mid-InfraRed Instrument (MIRI) mounted on the NASA/ESA/CSA James Webb Space Telescope. The image reveals details about the object that is 1.5 million light-years away from Earth. Continue reading to more about the neighbouring galaxy and research findings.About galaxy findingsAccording to the ESA report. NGC 6822 is the nearest galactic neighbour to Milky Way. The galaxy has exceptionally low metallicity, showcasing predominant hydrogen and helium elements. Low-metallicity objects like NGC 6822 have a crucial role in unveiling insights into the early universe. With hy...

Milky Way Galaxy and signs of life and water: Check out what this study found

[ad_1] A many as 1/3rd of the planets revolving around the most common stars across the Milky Way Galaxy may have liquid water and can possibly harbour life, according to a study based on latest telescope data. Most of the common stars in our galaxy are smaller and comparatively cooler. They are sporting just half the mass of the Sun at most. Billions of planets revolve around these common dwarf stars.Two-thirds of the planets around these ubiquitous small stars could be roasted by tidal extremes, sterilising them, shows the analysis which was published in the journal Proceedings of the National Academy of Sciences. Sheila Sagear, a doctoral student at the University of Florida (UF) in the US, said "I think this result is really important for the next decade of exoplanet research, becau...

Alien fossils on Earth? Here is TRUTH

[ad_1] Humans have always been fascinated by the idea of extraterrestrial life. As technology advanced, we have taken many steps in trying to understand it. Advance in technology keeps providing new opportunities to do so. We have held many observations of Venus and Mars and soon NASA will be sending missions to explore the Moons of Saturn and Uranus to know if life exists, or ever existed, on these celestial bodies. We have also spent a substantial amount of time observing outside the solar system and even other galaxies just to find planets similar to the Earth which might be able to sustain life. Amazingly, a recent study claims that evidence of alien life might well exist on Earth itself - in the form of alien fossils!A study was published in the International Journal of Astronomy t...

NASA’s James Webb Telescope discovers Galaxy that mirrors Milky Way

[ad_1] Researchers utilizing early data from the James Webb Space Telescope have discovered a young galaxy that resembles the early stages of our Milky Way Galaxy. Named "The Sparkler", the galaxy is embedded in a network of globular clusters and satellite galaxies and appears to be consuming them as it expands. The findings have been published in the Monthly Notices of the Royal Astronomical Society.Our Milky Way Galaxy hosts around 200 globular clusters right now. While the Sparkler galaxy is named for its two dozen orbiting globular clusters, "The Sparkler" offers a rare glimpse into the formation history of the Milky Way during its early stages. Globular clusters are the dense collections of approximately one million stars providing valuable information in this regard, the Royal As...

Hubble Space Telescope gets up close and personal with our neighbours

[ad_1] By getting to know our neighbours out in space, astronomers can determine what types of stars reside in various nearby galaxies and Hubble Space Telescope is helping map out the local structure of the Universe. Recently NASA has released an image of galaxy LEDA 48062 in the constellation Perseus by the Hubble Space Telescope. In the Image, LEDA 48062 is the faint, sparse, amorphous galaxy on the right side of the image, and it is accompanied by a more sharply defined neighbor on the left, the large, disc-like lenticular galaxy UGC 8603. A smattering of more distant galaxies also litters the background, and a handful of foreground stars are also visible throughout the image. The center of attraction in the image are stars surrounded by four sharp points. These points are call...
