New research adds a wrinkle to our understanding of the origins of matter in the Milky Way

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 … Read more

The give and take of mega-flares from stars

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 … Read more

EFFECTS OF BLACK HOLES BEYOND THEIR OWN GALAXIES

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 … Read more

ASTEROID 16 PSYCHE MIGHT NOT BE WHAT SCIENTISTS EXPECTED

asteroid 16 psyche

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 … Read more

FOR THE FIRST TIME, ASTRONOMERS HAVE OBSERVED ALFVEN WAVES IN THE PHOTOSPHERE OF THE SUN

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.  … Read more

MIRROR-SYMMETRY VIOLATION IN BOUND NUCLEAR GROUND STATES

exotic matter

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.

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 … Read more
