A solar storm has such power that it can destroy many electrical equipments on earth and can cause an internet blackout. Solar storm impact can create severe problems on earth like Grid failure. An Indian researcher Sangeetha Abdu Jythin said that in 2021 a massive solar storm is likely coming and the internet, which is… Continue reading Internet Blackout Due To A Solar Storm
Using the Multi-Unit Spectroscopic Explorer (MUSE), German astronomers have performed spectroscopic observations of a blue compact galaxy known as Haro 14. Results of the study, presented in a paper published August 20 on arXiv.org, shed more light on the galaxy’s morphology and its stellar populations. Blue compact galaxies (BCGs) are about a 10th of the… Continue reading MUSE observations of the blue compact dwarf galaxy Haro 14
A team of astronomers at the ARC Center of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) found that galaxies pollute the environment they exist in. Alex Cameron and Deanne Fisher lead researcher team used a new imaging system, at WM Keck Observatory in Hawaii to confirm that what flows into a galaxy… Continue reading How Star Making Process Is Polluting The Cosmos?
Comet ATLAS, also known as C/2019 Y4 ATLAS, was first discovered on December 28, 2019, by a reflecting telescope atop Mauna Loa in Hawaii as part of the Asteroid Terrestrial-impact Last Alert System (ATLAS). By May 2020 Comet ATLAS was visible to the naked eye as it grew brighter, the Long-period comet ATLAS disintegrated just… Continue reading A Tail From Collapse Of Comet ATLAS
Oumuamua is the first known interstellar object detected passing through the solar system. When Astronomers first detected it in the year 2017, it was too late to study it properly. But within that brief period, it exhibited some unexpected properties which left astronomers scratching their heads. Its elongated shape, lack of coma and facts that… Continue reading A FAST RESPONSE INTERCEPTOR SPACECRAFT TO STUDY INTERSTELLAR VISITORS LIKE OUMUAMUA
New findings published this week in Physical Review Letters suggest that carbon, oxygen, and hydrogen cosmic rays travel through the galaxy toward Earth in a similar way, but, surprisingly, that iron arrives at Earth differently. Learning more about how cosmic rays move through the galaxy helps address a fundamental, lingering question in astrophysics: How is… Continue reading New research adds a wrinkle to our understanding of the origins of matter in the Milky Way
The long relationships between stars and the planets around them—including the Sun and the Earth—maybe even more complex than previously thought. This is one conclusion of a new study involving thousands of stars using NASA’s Chandra X-ray Observatory. By conducting the largest survey ever of star-forming regions in X-rays, a team of researchers has helped… Continue reading The give and take of mega-flares from stars
This image, taken with Hubble’s Wide Field Camera 3, features the spiral galaxy NGC 4680. Two other galaxies, at the far right and bottom centre of the image, flank NGC 4680. NGC 4680 enjoyed a wave of attention in 1997, as it played host to a supernova explosion known as SN 1997bp. Australian amateur astronomer… Continue reading Image: Hubble sees a spiral in good company
Exploration of ocean worlds has become a hot topic of late, primarily due to their role as a potential harbour for alien life. Moons that have confirmed subsurface oceans garner much of the attention, such as Enceladus and Europa. But they may not be the only ones. Uranus’ larger moons—Miranda, Ariel and Umbriel could potentially… Continue reading What mission could detect oceans at Uranus’ moons?
At the heart of almost every sufficiently massive galaxy, there is a black hole whose gravitational field, although very intense, affects only a small region around the centre of the galaxy. Even though these objects are thousands of millions of times smaller than their host galaxies, our current view is that the Universe can be… Continue reading EFFECTS OF BLACK HOLES BEYOND THEIR OWN GALAXIES
The widely studied metallic asteroid known as 16 Psyche was long thought to be the exposed iron core of a small planet that failed to form during the solar system’s earliest days. But new University of Arizona-led research suggests that the asteroid might not be as metallic or dense as once thought and hints at… Continue reading ASTEROID 16 PSYCHE MIGHT NOT BE WHAT SCIENTISTS EXPECTED
An international group of collaborators, including scientists from NASA’s Jet Propulsion Laboratory and The University of New Mexico, have discovered a new, temperate sub-Neptune sized exoplanet with a 24-day orbital period orbiting a nearby M dwarf star. The recent discovery offers exciting research opportunities thanks to the planet’s substantial atmosphere, small star, and how fast… Continue reading SCIENTISTS DISCOVER A NEW EXOPLANET WITH A RIPE ATMOSPHERE
NASA’s Juno spacecraft flew closer to Jupiter’s largest moon than any other in more than two decades, offering dramatic glimpses of the icy orb. The first two images from NASA Juno’s June 7, 2021, flyby of Jupiter’s giant moon Ganymede have been received on Earth. The photos – one from the Jupiter orbiter’s JunoCam imager… Continue reading NASA’S JUNO SPACECRAFT CAPTURED SOME DRAMATIC IMAGES OF THE ICY ORB, GANYMEDE
As we all know, the Sun is a giant ball of plasma, and like any plasma, it should support Alfven waves. Alfven waves are waves in a plasma where the ions move in response to tension from a magnetic field. Scientists predicted it 50 years ago until now we had not been able to see them. … Continue reading FOR THE FIRST TIME, ASTRONOMERS HAVE OBSERVED ALFVEN WAVES IN THE PHOTOSPHERE OF THE SUN
Imagine if your home could be built in days. 3D printing has the potential to build your house from the ground up faster and for less money than a conventional home which means amongst other things, no more smoothing concrete by hand. The technology can physically produce a product of almost any shape based on… Continue reading 3D Printing Future Of Building Home
