VLA Provides New Insights into Solar Flares

Astronomers Reveal New Insights into Solar Flares

Using the Karl G. Jansky Very Large Array Radio Telescope, along with other telescopes at ultraviolet and X-ray wavelengths, astronomers reveal new insights into solar flares. Astronomers have made a significant step toward confirming a proposed explanation for how solar flares accelerate charged particles to speeds nearly that of light. This important advance was made […]

Astronomers Image the Expanding Shell of Supernova SN 2011dh

Optical Image of Galaxy Messier 51

Using precise radio imaging techniques, astronomers from the Harvard-Smithsonian Center for Astrophysics have determined the size of the shock around supernova SN 2011dh and estimated its outward velocity. Supernovae, the explosive deaths of massive stars, are among the most momentous events in the cosmos because they disburse into space all of the chemical elements that […]

Scientists Develop a New Way to Deliver MicroRNAs for Cancer Treatment

Researchers Develop a New Way to Deliver MicroRNAs

By twisting RNA strands into a triple helix and embedding them in a biocompatible gel, researchers from MIT have developed a new way to shrink tumors in mice with an aggressive form of breast cancer. Twenty years ago, scientists discovered that short strands of RNA known as microRNA help cells to fine-tune their gene expression. […]

New Cassini Image Shows Tethys Dwarfed by Saturn and Its Rings

New Cassini Image of Tethys and Saturn's Rings

This newly released Cassini image shows Tethys dwarfed by Saturn and its rings. Tethys, dwarfed by the scale of Saturn and its rings, appears as an elegant crescent in this image taken by NASA’s Cassini Spacecraft. Views like this are impossible from Earth, where we only see Saturn’s moons as (more or less) fully illuminated […]

Magnified Image Reveals the Faintest Known Galaxy from the Early Universe

Hubble Finds Faint Compact Galaxy in the Early Universe

Using NASA’s Hubble and Spitzer Space telescopes, astronomers have discovered the faintest object ever seen in the early universe. It existed about 400 million years after the big bang, 13.8 billion years ago. The team has nicknamed the object Tayna, which means “first-born” in Aymara, a language spoken in the Andes and Altiplano regions of […]

New Strategy to Better Protect Cancer Patients from the Flu

New Vaccine Better Protects Cancer Patients from Flu

Scientists from Yale University have developed a new vaccine strategy that reduces the risk of flu infections in cancer patients at highest risk for influenza. The findings were presented December 6 at the 57th annual meeting of the American Society of Hematology in Orlando, Florida. Patients with cancers of the immune system, like multiple myeloma, […]

Cassini Captures Infrared View of Saturn’s Moon Titan

New Cassini Image of Saturn's Moon Titan

This newly released composite image from NASA’s Cassini Spacecraft shows an infrared view of Saturn’s moon Titan. This new image was acquired during the mission’s “T-114” flyby on November 13, 2015. The spacecraft’s visual and infrared mapping spectrometer (VIMS) instrument made these observations, in which blue represents wavelengths centered at 1.3 microns, green represents 2.0 […]

New Horizons Reveals New Close-Up Images of Pluto

The Mountainous Shoreline of Sputnik Planum on Pluto

New images from NASA’s New Horizons Spacecraft are the sharpest views of Pluto it obtained during its July flyby – and the best close-ups of Pluto that humans may see for decades. Each week the piano-sized New Horizons spacecraft transmits data stored on its digital recorders from its flight through the Pluto system on July […]

Hubble Image of the Week: Spiral Galaxy NGC 7252

New Hubble Image of Spiral Galaxy NGC 7252

This newly released Hubble image shows spiral galaxy NGC 7252, which is located in the Aquarius constellation. Only rarely does an astronomical object have a political association. However, the spiral galaxy NGC 7252 acquired exactly that when it was given an unusual nickname. In December 1953, the US President Dwight D. Eisenhower gave a speech […]

Astronomers Measure Magnetic Fields at Sagittarius A*

Telescope Reveals Magnetic Fields at Milky Way's Central Black Hole

Using the Event Horizon Telescope, astronomers have measured the magnetic fields just outside the event horizon of Sagittarius A* for the first time. Most people think of black holes as giant vacuum cleaners sucking in everything that gets too close. But the supermassive black holes at the centers of galaxies are more like cosmic engines, […]

Yale Study Shows Protein IL-18 Contributes to Colitis

Researchers Identify Key Protein That Contributes to Colitis

New research from Yale University identifies that the protein IL-18 plays a key part in the development of the colitis. The cause of Ulcerative Colitis, a debilitating disease of the intestine, is unclear. A Yale-led study has illuminated the role of a protein that plays a key part in the development of the condition. The […]

Hubble Peers Through the Luminous Core of NGC 2768

Hubble Views NGC 2768

This new Hubble image shows elliptical galaxy NGC 2768. Like a lighthouse in the fog, the luminous core of NGC 2768 slowly fades outwards to a dull white haze in this image taken by the NASA/ESA Hubble Space Telescope. NGC 2768 is an elliptical galaxy in the constellation of Ursa Major (The Great Bear). It […]

New Research Reveals the Mystery of Missing Ordinary Matter

Study Details the Mystery of Ordinary Matter

New research shows that the majority of missing ordinary matter is found in the form of a very hot gas associated with intergalactic filaments. Matter known as ordinary, which makes up everything we know, corresponds to only 5% of the Universe. Approximately half of this percentage still eluded detection. Numerical simulations made it possible to […]

Scientists Overcome Key CRISPR-Cas9 Genome Editing Hurdle

Researchers Develop a Highly Specific Genome-Editing Tool

Using structural knowledge of Cas9, scientists have overcome a key CRISPR-Cas9 genome editing hurdle and developed a highly specific genome-editing tool. Researchers at the Broad Institute of MIT and Harvard and the McGovern Institute for Brain Research at MIT have engineered changes to the revolutionary CRISPR-Cas9 genome editing system that significantly cut down on “off-target” […]

Yale Researchers Find a Soft Spot in the Nazca Plate

Researchers Find a Soft Spot in a Tectonic Slab

Using land-based seismic stations, researchers from Yale University found that part of the Nazca Plate weakened and deformed as it bent and slid under the adjoining South American Plate. The Earth’s tectonic plates may be more flexible than previously thought as they slide underneath each other and dive deep below the surface, according to new […]
