Researchers Use Graphene in Photodetectors

Graphene Used in Photodetectors

A newly published study details how graphene can be used in photodetectors to convert optical signals to electrical signals in integrated optoelectronic computer chips. Graphene — which consists of atom-thick sheets of carbon atoms arranged hexagonally — is the new wonder material: Flexible, lightweight and incredibly conductive electrically, it’s also the strongest material known to […]

Microbe Stays Forever Young by Rejuvenating Every Time It Reproduces

Microbe Stays Forever Young by Rejuvenating Every Time it Reproduces

Scientists at the Max Planck Institute have discovered a microbe that is rejuvenated every time it reproduces. While aging remains an inevitable fact of life, Max Planck researchers have discovered a microbe that stays forever young by rejuvenating every time it reproduces. The findings provide fundamental insights into the mechanisms of aging. In general, even […]

A Natural Example of a Functioning Gear Mechanism Discovered in an Insect

Natural Example of a Functioning Gear Mechanism Discovered in an Insect

Scientists from the University of Cambridge have discovered a natural example of a functioning gear mechanism in an insect. Previously believed to be only man-made, a natural example of a functioning gear mechanism has been discovered in a common insect – showing that evolution developed interlocking cogs long before we did. The juvenile Issus – […]

Dwarf Galaxy M60-UCD1 – The Densest Galaxy

Hubble Image of Dwarf Galaxy M60 UDC1

In a newly published study, astronomers detail the discovery of an ultra-compact dwarf galaxy, called M60-UCD1, that has a stellar mass density of over one hundred stars per cubic light-year, making it the densest known galaxy. Our nearest neighbor star, Proxima Centauri, is about 4.2 light-years away. This distance is typical (on average) between stars […]

Researchers Discover Over 600 “Red Nugget” Galaxy Candidates

Hubble Views Red Nugget Galaxies

Using the Sloan Digital Sky Survey database, researchers discovered more than 600 “red nugget” galaxy candidates located at distances of 2.5 to 5.7 billion light-years from Earth. Cambridge, Massachusetts – In 2005 the Hubble Space Telescope spotted unusually small galaxies densely packed with red stars in the distant, young universe. They were nicknamed “red nuggets,” […]

Hubble Reveals Largest Known Group of Star Clusters, Clues to Dark Matter

Hubble Uncovers Largest Known Group of Star Clusters

Using the Hubble Space Telescope, astronomers have uncovered the largest known group of star clusters and have confirmed that such compact groupings can be used as reliable tracers for dark matter. NASA’s Hubble Space Telescope has uncovered the largest known population of globular star clusters, an estimated 160,000, swarming like bees inside the crowded core […]

It’s Official – Voyager 1 Has Entered Interstellar Space

NASAs Voyager 1 Spacecraft Enters Interstellar Space

A newly published study has confirmed that the 36-year-old NASA Voyager 1 spacecraft has left our solar system and has entered interstellar space. Pasadena, California — NASA’s Voyager 1 spacecraft officially is the first human-made object to venture into interstellar space. The 36-year-old probe is about 12 billion miles (19 billion kilometers) from our sun. […]

Detailed 3D Map Reveals Peanut Shape of Milky Way’s Inner Regions

Astronomers Discover that the Inner Regions of Milky Way Galaxy Have a Peanut Like Shape

Using ESO data, two groups of scientists have produced detailed three-dimensional images of the stars that form the inner regions of our Milky Way. Two groups of astronomers have used data from ESO telescopes to make the best three-dimensional map yet of the central parts of the Milky Way. They have found that the inner […]

Could Life on Earth Have Originated from Somewhere Else?

Could Life on Earth Have Originated from Somewhere Else

New research presented at the European Planetary Science Congress at UCL examines whether life forms would be able to survive an impact with the surface of the Earth, opening the door to the possibility that life did not originate on Earth but came from elsewhere in the universe. It sounds like science fiction, but the […]

Spitzer Reveals That Asteroid Don Quixote is a Comet

Astronomers Reveal Asteroid Don Quixote is a Comet

Data from NASA’s Spitzer Space Telescope helped astronomers discover that the large asteroid called Don Quixote is in fact a comet. For 30 years, a large near-Earth asteroid wandered its lone, intrepid path, passing before the scrutinizing eyes of scientists armed with telescopes while keeping something to itself. The object, known as Don Quixote, whose […]

Computer Models Help Explain Why Disk Galaxies Eventually Look Alike

Astronomers Discover Why Disk Galaxies Look Alike

In a newly published study, researchers detail how they developed and used computer models simulating galaxy evolution to help explain why all disk galaxies eventually look the same. Ames, Iowa – It happens to all kinds of flat, disk galaxies – whether they’re big, little, isolated or crowded in a cluster. They all grow out […]

New Research Explores the Possibility of Detecting Biomarkers on Distant Planets

New Research Aims to Detect Biomarkers on Distant Planets

New research presented to the European Planetary Science Congress at UCL aims to explore how atmospheric biomarkers from faraway planets might be detected in the future. On Earth, life leaves tell-tale signals in the atmosphere. Photosynthesis is ultimately responsible for the high oxygen levels and the thick ozone layer. Microbes emit methane and nitrous oxide […]
