A Cosmic Riddle: Why is the Milky Way galaxy becoming gaseous?

Astronomers have discovered a strange excess of gas in the Milky Way galaxy. Using 10-year data from NASA's Hubble Space Telescope, the team of astronomers concluded that more gas is flowing into and out of our galaxy. Instead of a balance between gas entry and exit, there is a significant imbalance, although the team behind this finding has not yet …

Astronomers discover filaments of the cosmic web that held the early universe together

Using a simulation, astronomers illuminate the faint gaseous filaments that make up the cosmic web in a huge cluster of galaxies. The Hubble Space Telescope's wide-field camera observed Saturn in June, when the planet approached Earth the next year, about 1.36 billion kilometers away. An artistic impression of the massive bursts of ionizing radiation exploding from the center of the …

The cosmic web drives stars and supermassive black holes into place

<! – -> Astronomers now view our universe as a cosmic web consisting of massive filaments of galaxies separated by huge cavities. We do not know exactly how this cosmic web is. Most of our research has been done using computational models, in particular the model of cold dark matter for galaxy formation, which is currently favored by most cosmologists. …

Astronomers spy two baby stars in a cosmic pretzel

The Atacama Large Millimeter / Submillimeter Array has captured this unprecedented image of two circumstellar disks on which baby stars grow and feed on the material of their surrounding birth disc. This is an artistic representation of what a Neptune-sized Moon would look like when it orbits the gas giant exoplanet Kepler-1625b in a star system 8,000 light-years from Earth. …

Cosmic Danger: Go to Mars before it's too late, warns space expert – the earth is in danger | Science | news

An asteroid strike 66 million years ago erased two-thirds of Earth's life, triggering a series of events that ended dinosaur rule. Other cosmic dangers such as solar storms and gamma rays can be equally devastating to the planet. Because of these threats, Dr. Weronika Śliwa from the Copernicus Science Center Planetarium in Warsaw says it is unwise for the earth …

Huge cosmic structures already existed when the universe was a baby

Astronomers have discovered the oldest galaxy cluster ever seen dating from the early Universe. The discovery, which could explain the shape of the modern cosmos, reveals 12 galaxies that existed in a cluster 13 billion years ago – nearly 700 million years after the Big Bang. We can now see them because they are so far away in the expanding …

Gargantuan Black Hole Shreds Star in rare cosmic discovery

A NASA Space Telescope chasing extraterrestrial planets has just stumbled into a rare cosmic scene: A star is devoured by a monster Black Hole . The discovery of NASA's Transiting Exoplanet Survey Satellite (TESS) provides a rare glimpse into the death throes of a star torn apart by the catastrophic gravitational forces of a supermassive black hole. The action takes …
