Filling the gap between the cosmic microwave background and the first galaxy
A new image of the background radiation of cosmic microwaves (semi-ski image on the left, close-up on the right) adds high resolution to the early images of the Planck satellite from the Atacama Cosmological Telescope. Orange and blue represent more or less intense radiation, revealing new features of cosmic density. The Milky Way appears as a red band with a…

Cosmic data suggests that the universe has become “more cluttered and more complicated”.
Credit: UNSPLASH/CC0 Public domain Through the history of the universe, powerful power has acted on substances, and the universe has been re -formed into a net with a more complicated structure. By the way, new research led by Joshua Kim, Matavaselil, the University of Pennsylvania, and co -researchers at the Lawrence Berkeley National Institute is about 13.8 billion years since…

The carbon in our bodies likely left the galaxy and returned on a cosmic conveyor belt.
An image of the star-dense part of our galaxy, the Milky Way, taken by the Hubble Space Telescope. Credit: NASA/ESA/Hubble Heritage Team Life on Earth cannot exist without carbon. However, carbon itself cannot exist without stars. Almost all elements except hydrogen and helium (including carbon, oxygen, and iron) exist only because they were forged in stellar furnaces and then ejected…

Innovative model offers new way for astronomers to analyze powerful cosmic explosions
The explosion of a massive star leads to the ejection of its outer shell, and this “ejecta” expands outward over time and interacts with the star’s surrounding medium upon its death. This interaction creates two shock waves and a contact discontinuity (collectively known as a “shell”) that dissipates kinetic energy in exchange for producing more light. Eric Coughlin’s new model…

New cosmic distance catalogue may shed light on mysteries of the universe’s formation
The William Herschel Telescope, La Palma, Spain. Courtesy of the PAUS team. A new catalog was published today that provides information on millions of distant galaxies, determining their distances with unprecedented precision, across fields and depths never before explored. The catalogue is the product of the Accelerated Astrophysics Survey (PAUS), an international collaboration project led by the Institute for Space…

As a result of a cosmic upheaval, a new star is about to be born in the sky
Anthony R. Wood, The Philadelphia Inquirer Credit: Unsplash/CC0 Public Domain Astrophysicists say that any moment now, a new star as bright as Polaris will appear in the night sky — the result of a cosmic explosion that happened thousands of years ago in a distant constellation. NASA scientist Rebecca Hounsell calls it a “once-in-a-lifetime event that will spawn many new…
