Dragonfly 44 – A Massive Galaxy That Consists Almost Entirely of Dark Matter

Galaxy Dragonfly 44

An international team of astronomers has discovered a massive galaxy that consists almost entirely of dark matter. The galaxy, Dragonfly 44, is located in the nearby Coma constellation and had been overlooked until last year because of its unusual composition: It is a diffuse “blob” about the size of the Milky Way, but with far […]

Earth-Sized Planet Proxima b Might be Habitable

Planet Found in Habitable Zone Around Nearest Star

Scientists reveal that a newly discovered, roughly Earth-sized planet orbiting our nearest neighboring star might be habitable. Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and […]

New Reserach Reveals How Zika Virus Causes Fetal Brain Damage

Yale Reserachers Discover How Zika Virus Causes Fetal Brain Damage

In a newly published study, researchers from Yale University report that infection by the Zika virus diverts a key protein necessary for neural cell division in the developing human fetus, thereby causing the birth defect microcephaly. The findings suggest that Zika virus might be susceptible to existing antiviral drugs that may prevent disruption to the […]

NASA Telescopes Reveal a Surprising Blazar Connection

A Surprising Blazar Connection Revealed

Using data from from NASA’s Wide-field Infrared Survey Explorer (WISE) and Fermi Gamma-ray Space Telescope, astronomers studying distant galaxies powered by monster black holes have uncovered an unexpected link between two very different wavelengths of the light they emit, the mid-infrared and gamma rays. The discovery has enabled the researchers to uncover dozens of new […]

Yale Scientists Discover a New Therapy for a Chronic Brain Disease

Yale Biologists Uncover Marker for a Chronic Brain Disease

Yale scientists have discovered a new and effective therapy for cerebral cavernous malformations. A team of researchers led by Yale professor of pathology Wang Min have pinpointed a marker that contributes to a chronic condition affecting the brain. Known as cerebral cavernous malformations, the condition is characterized by a tangle of capillaries in the brain’s […]

New Study Shows ‘Smoke Waves’ Will Affect Millions in the Coming Decades

US Counties Risk Exposure to Pollution from Wildfires

Newly published research identifies the western U.S. counties with the highest risk of exposure to pollution from wildfires. Wildfires threaten more than land and homes. The smoke they produce contains fine particles (PM2.5) that can poison the air for hundreds of miles. Air pollution from the 2016 Fort McMurray fire in northern Alberta, Canada, sent […]

MIT Biological Engineers Program Human Cells to Store Complex Histories in Their DNA

Recording Analog Memories in Human Cells

Newly published research details how biological engineers from MIT developed a way to record complex histories in the DNA of human cells, allowing them to retrieve “memories” of past events by sequencing the DNA. This analog memory storage system — the first that can record the duration and/or intensity of events in human cells — […]

Study Suggests Habitable Zone Alone Isn’t Sufficient to Support Life

Planetary Habitability Depends on Internal Planet Temperature

New research from Yale University suggests that simply being in the habitable zone isn’t sufficient to support life. A planet also must start with an internal temperature that is just right. The search for habitable, alien worlds needs to make room for a second “Goldilocks,” according to a Yale University researcher. For decades, it has […]

Hubble Views Dwarf Galaxy NGC 5264

Dwarf Galaxy NGC 5264

This new Hubble image captures the glow of distant stars within NGC 5264, a dwarf galaxy located just over 15 million light-years away in the constellation of Hydra (The Sea Serpent). Dwarf galaxies like NGC 5264 typically possess around a billion stars — just one per cent of the number of stars found within the […]

Exoplanet GJ 1132b Might Have a Thin Oxygen Atmosphere

Venus-like Exoplanet GJ 1132b Might Have Oxygen Atmosphere

New research from the Harvard-Smithsonian Center for Astrophysics reveals that the Venus-like Exoplanet GJ 1132b might possess a thin, oxygen atmosphere – but no life due to its extreme heat. The distant planet GJ 1132b intrigued astronomers when it was discovered last year. Located just 39 light-years from Earth, it might have an atmosphere despite […]

Chandra Data Raises Questions about the Timing and Origin of Supernova Remnant G11.2-0.3

New Chandra Data of the Supernova Remnant G11

New Chandra data of the supernova remnant G11.2-0.3 raise new questions about the timing of its origin. Chandra observations show that dense gas clouds lie along the line of sight between Earth and G11.2-0.3, meaning that the supernova explosion would have been too faint to be seen with the naked eye from Earth. A new […]

Van Allen Probes View Supercharged Radiation Belt

Van Allen Probes Catch Rare Glimpse of Supercharged Radiation Belt

New research details how a shockwave created by the driving force of a coronal mass ejection from the sun – struck the outermost radiation belt, triggering the greatest geomagnetic storm of the preceding decade. Our planet is nestled in the center of two immense, concentric doughnuts of powerful radiation: the Van Allen radiation belts, which […]

Iris Nebula Offers Clues to the Building Blocks of Life

Molecules in Nebula NGC 7023 Offer Clues to the Building Blocks of Life

Using data from NASA’s Stratospheric Observatory for Infrared Astronomy and other observatories, astronomers reveal how a particular type of organic molecules, the raw materials for life – could develop in space. This information could help scientists better understand how life could have developed on Earth. Bavo Croiset of Leiden University in the Netherlands and his […]

Hubble Discovers Two Dwarf Galaxies Moving into the Milky Way

Hubble Uncovers a Galaxy Pair Moving into the Milky Way

A team of astronomers has discovered two dwarf galaxies that have traveled from the remote hinterlands of space to the Milky Way. NASA’s Hubble Space Telescope has uncovered two tiny dwarf galaxies that have wandered from a vast cosmic wilderness into a nearby “big city” packed with galaxies. After being quiescent for billions of years, […]

ALMA Images the Planetesimal Belt around HR8799

Resolving the Planetesimal Belt of HR 8799

Using the ALMA submillimeter array, astronomers image the disk around HR8799 with a spatial scale as small as only thirty-two au, enough to probe the inner zones of the disk. Planets develop from the dusty placental disk of material that surrounds a star after it begins to shine. The dust in that disk, according to […]

Hubble Telescope Views Exploding White Dwarf Star

Hubble Views Exploding White Dwarf

This newly released Hubble image shows the aftermath of an exploding star that was located in the Large Magellanic Cloud. Several thousand years ago, a star some 160,000 light-years away from us exploded, scattering stellar shrapnel across the sky. The aftermath of this energetic detonation is shown here in this striking image from the NASA/ESA […]

New Research From NASA Suggests Venus May Have Been Habitable

NASA Suggests Venus May Have Been Habitable

New research from NASA suggests that Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to 2 billion years of its early history. The findings, published this week in the journal Geophysical Research Letters, were obtained with a model similar to the type used to predict future climate change on […]
