Astronomers find growing number of Starlink satellite tracks

Enlarge / A Starlink track running across the Andromeda galaxy. SpaceX’s Starlink Internet service will require a dense constellation of satellites to provide consistent, low-latency connectivity. The system already has over 1,500 satellites in orbit and has received approval to operate 12,000 of them. And that has astronomers worried. Although SpaceX has taken steps to … Read more

UC Santa Cruz astronomers poised to join NASA’s search for signs of life in distant galaxies with new telescope   – Monterey Herald

Folded up inside its rocket-like origami, the James Webb Space Telescope lies in wait. The $10 billion instrument is set to launch as early as Christmas Eve to a gravitational sweet spot nearly a million miles from Earth, where it will tag along with us in orbit around the sun. During its journey, the telescope … Read more

SANTA CRUZ — Folded up inside its rocket like origami, the James Webb Space Telescope lies in wait. The $10 billion instrument is set to launch as early as Christmas Eve to a gravitational sweet spot nearly a million miles from Earth, where it will tag along with us in orbit around the sun.

Polish astronomers determined the mass of a hidden gravitational object

We deal with microlensing when there is an invisible object between the observer and the observed astronomical phenomenon (at the intersection of the vision axis) with a mass large enough to exert a gravitational influence on the light flowing from there. The result is then a characteristic distortion of the image of the observed object … Read more

Astronomers Feature In Detail Gigantic Cluster Of Galaxies

Italian astronomers performed X-ray observations of the massive cluster of galaxies ClG-J104803.7 + 313843, using ESA’s XMM-Newton spacecraft. The results of the observational campaign shed more light on the properties of this cluster. Galaxy clusters contain up to thousands of galaxies bound together by gravity. They are the largest known gravitationally binding structures in the … Read more

Astronomers Discover a True Shipyard of Galaxy in the Distant Universe

An international team of astronomers reports the discovery of objects that appear to be an emerging accumulation of forming galaxies – known as a protocluster. “This discovery is an important step towards our ultimate goal: to understand the assembly of galaxy clusters, the most massive structures that exist in the universe,” said Brenda Frye, associate … Read more

Astronomers Discover What’s Killing Galaxies

Astronomers examining the nearby Universe with the help of the Atacama Large Millimeter / submillimeter Array (ALMA) have just completed the largest high-resolution star-forming fuel survey ever conducted in galaxy clusters. But, more importantly, they’re dealing with an ancient astrophysical mystery: what’s killing galaxies? The research, which provides the clearest evidence to date that extreme … Read more

The Strangest Combination of Planetary Orbits Ever Discovered by Astronomers

The process of finding thousands of planets around other stars has been one of the processes that most surprise astronomers with new and unusual discoveries. However, even expecting the unexpected, the planetary system HD 3167 is a shock – with one planet behaving normally, a second orbiting perpendicular to the first, while a third orbiting … Read more

Astronomers Detect Giant Impact Signal In Near Planetary System

Young planetary systems often experience extreme growing pains as babies’ bodies collide and fuse together to form progressively larger planets. In our own solar system, the Earth and moon are believed to be products of this kind of giant impact. Astronomers assume that such collisions should be common in early systems, but they have been … Read more

A Warm Baby Neptune Provides Astronomers with Clues to Its Birth

The star AU Microscopii is a baby red dwarf star located about 32 light-years away in the southern constellation Microscopium, the Microscope. It is only 22 million years old and surrounded by a field of planetary debris, first observed in 2004 . Last year, independent teams discovered two exoplanets (AU Mic bec) orbiting the star. … Read more
