First Clear View Of A Boiling Cauldron Where Stars Are Born (Cosmology)

UMD-led team used NASA’s SOFIA telescope to capture high-resolution details of a star nursery in the Milky Way University of Maryland researchers created the first high-resolution image of an expanding bubble of hot plasma and ionized gas where stars are born. Previous low-resolution images did not clearly show the bubble or reveal how it expanded … Continue reading First Clear View Of A Boiling Cauldron Where Stars Are Born (Cosmology)

Picture Of The Week: Clash of the Titans (Cosmology)

A cataclysmic cosmic collision takes centre stage in this Picture of the Week. The image features the interacting galaxy pair IC 1623, which lies around 275 million light-years away in the constellation Cetus (The Whale). The two galaxies are in the final stages of merging, and astronomers expect a powerful inflow of gas to ignite … Continue reading Picture Of The Week: Clash of the Titans (Cosmology)

Thus A Cluster Emerges From The Cosmic Web (Cosmology)

An international team of astronomers used the National Science Foundation’s Green Bank Telescope and NASA’s Chandra X-ray Observatory to capture a snapshot of a massive cluster around the time it began to emerge from the cosmic web, nearly 10 billion. Years ago. The study is published in Mnras A sort of reverse dive: so we can … Continue reading Thus A Cluster Emerges From The Cosmic Web (Cosmology)

A New Type of Gravitational Wave Detector to Find Tennis Ballsized Black Holes (Cosmology)

A new type of gravitational wave detector to find tennis ballsized black holes straight out of the Big Bang “Detecting primordial black holes opens up new perspectives to understand the origin of the Universe, because these still hypothetical black holes are supposed to have formed just a few tiny fractions of a second after the … Continue reading A New Type of Gravitational Wave Detector to Find Tennis Ballsized Black Holes (Cosmology)

The Mystery Of The Missing Dark Matter (Cosmology)

New distance measurements of the diffuse spheroid galaxy Ngc 1052-Df2 place this galaxy at a distance of 72 million light years and confirm that the galaxy is practically devoid of dark matter, a very rare case in the galaxy landscape. This absence of dark matter compared to other galaxies suggests that dark matter exists as a … Continue reading The Mystery Of The Missing Dark Matter (Cosmology)

Is Dark Matter Real, Or Have We Misunderstood Gravity? (Cosmology)

For many years now, astronomers and physicists have been in a conflict. Is the mysterious dark matter that we observe deep in the Universe real, or is what we see the result of subtle deviations from the laws of gravity as we know them? In 2016, Dutch physicist Erik Verlinde proposed a theory of the … Continue reading Is Dark Matter Real, Or Have We Misunderstood Gravity? (Cosmology)

Primordial Black Holes Give Rise To Mu-Distortion Which Can Be Detected By Future Observations (Cosmology)

If you are a daily reader, you may have came across several articles on our website based on the formation of primordial black holes (PBHs). But, the most popular and natural scenario is, production of PBHs by the collapse of the clumps. In this scenario, PBHs production takes place by the collapse of large overdense … Continue reading Primordial Black Holes Give Rise To Mu-Distortion Which Can Be Detected By Future Observations (Cosmology)

Researchers Trace Dust Grain’s Journey Through Newborn Solar System (Cosmology)

Combining atomic-scale sample analysis and models simulating likely conditions in the nascent solar system, a new study reveals clues about the origin of crystals that formed more than 4.5 billion years ago. A research team led by the University of Arizona has reconstructed in unprecedented detail the history of a dust grain that formed during … Continue reading Researchers Trace Dust Grain’s Journey Through Newborn Solar System (Cosmology)

New Research Adds A Wrinkle to Our Understanding Of the Origins of Matter in the Milky Way (Cosmology)

New information about how different cosmic rays arrive at Earth hints at unique sources or propagation methods for different elements 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 … Continue reading New Research Adds A Wrinkle to Our Understanding Of the Origins of Matter in the Milky Way (Cosmology)
