Pre-Solar System Dust Found in the Atmosphere

June 15, 2018

A research team led by the University of Hawai’i at Mānoa’s School of Ocean and Earth Science and Technology say they have discovered the remains of the formation of the solar system in some interstellar dust. The dust particles, which were gathered in Earth’s atmosphere by NASA aircraft, are thought to have been cast off from […]

Astronomers Search for the Sun’s Long-Lost Solar Siblings

April 20, 2018

While a family reunion is highly unlikely, Australian and European astronomers are still trying to find our Sun’s long-lost solar siblings which are now scattered throughout the sky. To do so, the scientists examined the of some 350,000 stars in the Milky Way – as though they were mapping each star’s DNA. The sun was […]

Dark Matter Imaged; Shoe-String Theory; Metal in Mars Atmosphere

April 14, 2017

Dark Matter Filaments of Cosmic Web Imaged Two Canadian researchers say that they have constructed a composite image of dark matter filaments that make up what cosmologists call the cosmic web. Scientists have been finding evidence that our universe may be anything but random and that everything is actually organized and connected to each other […]

Is the Universe Connected By a Cosmic Web?

January 26, 2017

Some people think that the universe is just a hodge-podge of various celestial objects, such as planets, stars and galaxies. But over the years, scientists have found more evidence that the universe may be anything but random, and is actually more organized and interconnected—like an enormous spider web. Our place in the web Let’s start […]

Ants Goof Off Too; Milky Way Steals Stars; Astronomers Spot Exocomets

January 16, 2017

Ants Balance Work and Rest to Maintain Colony Ants have a reputation of being dedicated and hardworking creatures. But did you know that like humans, ants also seek to maintain a healthy balance of work and rest? While an ant colony appears to be filled with busy workers, according to new research, there are also […]

Black Hole Back Doors?; Io’s Atmosphere; No New Stars in Galaxy Center

August 5, 2016

Do Black Holes Have Back Doors? Most people describe a black hole as a cosmic object with gravity so strong that it sucks in any kind of material that comes close to it. What happens to stuff that is pulled into a black hole? Some scientists think that matter that enters a black hole gets […]

One Third of the World’s Population Unable to See Milky Way

June 13, 2016

Among my fondest memories of being a kid back in the 1960’s was taking a week or so of summer vacation to visit relatives at my grandfather’s farm in Herman, PA (about 65 km northeast of Pittsburgh). During my stay I would spend evenings lying on the freshly cut grass of my grandpa’s back yard, just looking up into […]

Astronomers Spot 80 of the Oldest Galaxies

March 14, 2016

Advancing technology is making it possible for scientists to investigate the early universe. About 200 million years after the Big Bang, it is thought that clumps of condensed primordial cold gas clouds provided material for the first stars to be born. As stars were created they formed small galaxies. An international team of researchers are […]

Science Scanner: Stars Younger than Thought, E-Cigarettes Not Really a Healthier Alternative, Red Grapes Help Burn Fat

February 6, 2015

Stars Are Younger than Thought A preliminary analysis of data gathered by the European Space Agency’s (ESA) Planck mission has shown that the first stars of our universe are younger than first thought. Scientists said data gathered by the Planck mission between 2009 and 2013 shows that the universe remained completely dark for about 550 […]
