'Cosmic cannibals' expel jets into space at 40 percent the speed of light      (via sciencedaily.com)     Original source 

Astronomers have measured the speed of fast-moving jets in space, crucial to star formation and the distribution of elements needed for life. The jets of matter, expelled by stars deemed 'cosmic cannibals', were measured to travel at over one-third of the speed of light -- thanks to a groundbreaking new experiment.

Signs of life would be detectable in single ice grain emitted from extraterrestrial moons      (via sciencedaily.com)     Original source 

Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.

Two of the Milky Way's earliest building blocks identified      (via sciencedaily.com)     Original source 

Astronomers have identified what could be two of the Milky Way's earliest building blocks: Named 'Shakti' and 'Shiva', these appear to be the remnants of two galaxies that merged between 12 and 13 billion years ago with an early version of the Milky Way, contributing to our home galaxy's initial growth. The new find is the astronomical equivalent of archeologists identifying traces of an initial settlement that grew into a large present-day city.

High school students contribute to exoplanet discovery      (via sciencedaily.com)     Original source 

A group of high school students from Oakland, California, made contributions to the field of exoplanet research. Researchers worked with the students to use backpack-sized digital smart telescopes. These young citizen scientists played a role in observing and confirming the nature of a warm and dense sub-Saturn planet, known as TIC 139270665 b, orbiting a metal-rich G2 star.

Scientists find one of the most ancient stars that formed in another galaxy      (via sciencedaily.com)     Original source 

The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your veins and the calcium in your teeth and the sodium powering your thoughts were all born in the heart of a long-dead star.

Astrophysicist's research could provide a hint in the search for dark matter      (via sciencedaily.com)     Original source 

Dark matter is one of science's greatest mysteries. Although it is believed to make up about 85 percent of the cosmos, scientists know very little about its fundamental nature. Research provides some of the most stringent constraints on the nature of dark matter yet. It also revealed a small hint of a signal that, if real, could be confirmed in the next decade or so.

Largest-ever map of universe's active supermassive black holes released      (via sciencedaily.com)     Original source 

Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ironically, some of the universe's brightest objects. The new map logs the location of about 1.3 million quasars in space and time, the furthest of which shone bright when the universe was only 1.5 billion years old. The work could help scientists better understand the properties of dark matter.
