How Star Making Process Is Polluting The Cosmos?

The DUVET Survey: Direct Te-based Metallicity Mapping of Metal-enriched Outflows and Metal-poor Inflows in Markarian 1486

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 … Read more

A FAST RESPONSE INTERCEPTOR SPACECRAFT TO STUDY INTERSTELLAR VISITORS LIKE OUMUAMUA

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 … Read more

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

HOW DID THE MOON FORM?

Our Moon is a jewel in our night sky. The night sky just wouldn’t feel right without the Moon. But the Moon wasn’t there all the time. So Where did our natural satellite come from? After the sun spun to light, the planets of the solar system began to form. But it took another hundred … Read more

WHY STUDY ASTEROIDS?

The scientific interest in asteroids is largely due to their status as the remnant debris from the inner solar system formation process. Because some of these objects can collide with the Earth, asteroids are also important for having significantly modified the Earth’s biosphere in the past. They will continue to do so in the future. … Read more
