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?

A Tail From Collapse Of Comet ATLAS
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
A FAST RESPONSE INTERCEPTOR SPACECRAFT TO STUDY INTERSTELLAR VISITORS LIKE OUMUAMUA
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 research adds a wrinkle to our understanding of the origins of matter in the Milky Way
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 give and take of mega-flares from stars
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
EFFECTS OF BLACK HOLES BEYOND THEIR OWN GALAXIES
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
ASTEROID 16 PSYCHE MIGHT NOT BE WHAT SCIENTISTS EXPECTED
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
FOR THE FIRST TIME, ASTRONOMERS HAVE OBSERVED ALFVEN WAVES IN THE PHOTOSPHERE OF THE SUN
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
MEASURING THE SPIN OF A BLACK HOLE
Astronomers are able to measure the masses of black holes in a relatively straightforward way: watching how matter moves in their vicinity (including other black holes), affected by the gravitational field.
TURBULENT SKIES OF NEARBY FAILED STAR SPOTTED BY THICK CLOUD BANDS
Scientists have spotted evidence of Jupiter-like stripes in the thick atmosphere of a nearby brown dwarf, a new study reports — and this evidence was gathered in a novel way.
WIND SPEED OF A BROWN DWARF MEASURED FOR THE FIRST TIME
For the first time ever, astronomers have measured wind speed on a brown dwarf, or “failed star,” an object heftier than a planet but not massive enough to host the fusion reactions that power stars.
A NEWFOUND BLACK HOLE IS THE CLOSEST ONE TO EARTH WE HAVE EVER FOUND
A newfound black hole may be the closest black hole to Earth, and you can spot its cosmic home in the night sky without a telescope.
MIRROR-SYMMETRY VIOLATION IN BOUND NUCLEAR GROUND STATES
The breakthrough by the researchers revealed that a symmetry that exists within the core of atoms is not as fundamental as scientists have believed. The discovery sheds light on the forces at work within the nucleus of atoms, opening the door to a greater understanding of the universe.
UNIVERSE MAY NOT BE EXPANDING UNIFORMLY IN EVERY DIRECTION
A new study using data from NASA’s Chandra X-ray Observatory and European Space Agency’s XMM-Newton challenges one of the fundamental ideas of cosmology that everything looks the same in all directions if you look over large enough distances.
EVEN STAR SYSTEMS HAVE IDENTITY CRISES
A double star system has been flipping between two alter egos, according to observations with Chandra X-ray Observatory and The Karl G. Jansky Very Large Array(VLA). Using nearly a decade and a half worth of Chandra data, researchers noticed that a stellar duo behaved like one type of object before switching its identity… Continue reading EVEN STAR SYSTEMS HAVE IDENTITY CRISES
