New IBEX Observations Determine the Strength of the Magnetic Field Outside the Heliosphere

IBEX Observations Pin Down Interstellar Magnetic Field
A newly published study uses IBEX data and simulations of the interstellar boundary to better describe space in our galactic neighborhood. Immediately after its 2008 launch, NASA’s Interstellar Boundary Explorer, or IBEX, spotted a curiosity in a thin slice of space: More particles streamed in through a long, skinny swath in the sky than anywhere […]

Astronomers Identify the Precise Location of a Fast Radio Burst in a Distant Galaxy

Radio Burst Reveals 'Missing Matter' in the Universe
An international team of astronomers used a combination of radio and optical telescopes to identify the precise location of a fast radio burst (FRB) in a distant galaxy, allowing them to conduct a unique census of the Universe’s matter content. Their result, published in today’s edition of Nature, confirms current cosmological models of the distribution […]

Gravitational Waves Could Soon be Detectable by Existing Radio Telescopes

Low-Frequency Gravitational Waves Could Soon be Detectable by Existing Radio Telescopes
A newly published study from the North American Nanohertz Observatory for Gravitational Waves reveals that low-frequency gravitational waves could soon be detectable by existing radio telescopes. The recent detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) came from two black holes, each about 30 times the mass of our sun, merging into […]

New Research Shows LIGO’s Twin Black Holes Might Have Been Born Inside a Single Star

Twin Black Holes Born Inside a Single Star
Newly published research from the Harvard-Smithsonian Center for Astrophysics suggests that the burst detected by LIGO occurred because the two black holes lived and died inside a single, massive star. On September 14, 2015, the Laser Interferometer Gravitational-wave Observatory (LIGO) detected gravitational waves from the merger of two black holes 29 and 36 times the […]

Astronomers Complete the ATLASGAL Survey of Milky Way

The Southern Plane of the Milky Way
Astronomers have completed the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). A spectacular new image of the Milky Way has been released to mark the completion of the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). The APEX telescope in Chile has mapped the full area of the Galactic Plane visible from […]

Astronomers Discover Distant Radio Galaxies via Gravitational Lensing

Radio Galaxies Being Gravitationally Lensed
A new study details how a team of X-ray astronomers used lensed radio galaxies to identify and study distant galaxies with active supermassive black hole nuclei. A lensing cluster is a gravitationally bound collection of galaxies, hundreds or even thousands, whose mass acts as a gravitational lens to collect and reimage the light of more […]

Cassini Measures Titan Surface Temperatures During Northern Winter and Spring

New Titan Temperature Lag Maps & Animation
Newly published research details the varying surface temperatures on Saturn’s moon Titan at two-year intervals, from 2004 to 2016. The measurements were made by the Composite Infrared Spectrometer (CIRS) instrument on NASA’s Cassini spacecraft. The maps show thermal infrared radiation (heat) coming from Titan’s surface at a wavelength of 19 microns, a spectral window at […]

Climate Change Threatens Boreal Coniferous Forests

Climate Change Threatens Dark Taiga
New research from the Max Planck Institute of Biochemistry reveals that Boreal coniferous forests could see increased occurrences of fire as a result of global warming, with deciduous trees becoming more dominant in the future. Climate change is transforming the Earth, particularly in high-latitude regions. The boreal coniferous forests of the northern hemisphere will witness […]

New Microfluidic Screening Device May Speed Up DNA Insertion in Bacteria

New Microfluidic Device May Speed Up DNA Insertion in Bacteria
In search of the ideal bacteria for use in a microbial fuel cell, researchers from MIT have developed a new microfluid device to quickly sort and identify the various strains. This technology, which could lead to a carbon-neutral method of harvesting energy for the grid from wastewater, may also be useful to doctors in identifying […]

Three Times the Fun: New Cassini Image of Tethys, Enceladus and Mimas

New Cassini Image of Tethys, Enceladus and Mimas
This newly released Cassini image shows Saturn’s moons Tethys, Enceladus and Mimas. Three of Saturn’s moons — Tethys, Enceladus and Mimas — are captured in this group photo from NASA’s Cassini spacecraft. Tethys (660 miles or 1,062 kilometers across) appears above the rings, while Enceladus (313 miles or 504 kilometers across) sits just below center. […]

Hubble Image of the Week – Blue Bubble in Carina

Hubble Views Wolf–Rayet Star WR 31a
This newly released Hubble image shows Wolf–Rayet star WR 31a. Sparkling at the center of this beautiful NASA/ESA Hubble Space Telescope image is a Wolf–Rayet star known as WR 31a, located about 30,000 light-years away in the constellation of Carina (The Keel). The distinctive blue bubble appearing to encircle WR 31a, and its uncatalogued stellar […]

Hubble Measures Rotation of ‘Super-Jupiter’ Exoplanet 2M1207b

Discovery of Rotational Modulations in the Planetary-Mass Companion 2M1207b
Using the Hubble Space Telescope, a team of astronomers has measured the rotation rate of an extreme exoplanet by observing the varied brightness in its atmosphere. This is the first measurement of the rotation of a massive exoplanet using direct imaging. “The result is very exciting,” said Daniel Apai of the University of Arizona in […]

Hubble Views the Young Star HBC 1

Hubble Views HBC 1
Surrounded by dust, this new Hubble image shows the young forming star known as HBC 1. The star is in an immature and adolescent phase of life, while most of a sun-like star’s life is spent in a stable stage comparable to human adulthood. In this view, HBC 1 illuminates a wispy reflection nebula known […]

New Horizons Reveals a Possible Ancient Ocean on Charon

Possible Ancient Ocean on Charon
New images from the New Horizons Spacecraft suggest that Pluto’s moon Charon once had a subsurface ocean that has long since frozen and expanded, pushing outward and causing the moon’s surface to stretch and fracture on a massive scale. The side of Pluto’s largest moon viewed by NASA’s passing New Horizons spacecraft in July 2015 […]

Physicists Test the Response Time of Electrons

Researchers Determine the Delay with Which Electrons in Atoms Respond to the Electromagnetic Forces of Light
Researchers from the Laboratory for Attosecond Physics generated for the first time visible flashes of light in attosecond dimensions. They dispatched the light-flashes to electrons in krypton atoms. Through the experiment the researchers have been able to display that the electrons, which are stimulated by the flashes, needed roughly 100 attoseconds to respond to the […]

Astronomers Discover Binary Star System That Produces the Longest Lasting Known Eclipse

Binary Star System Produces the Longest Lasting Eclipses Known
Astronomers have discovered a binary star system where, every 69 years, the sun disappears in a near-total eclipse that lasts for three and a half years. The unnamed binary star system nearly 10,000 light years from Earth and is known only by its astronomical catalog number TYC 2505-672-1. It sets a new record for both […]

MIT Develops New Imaging System with Open-Ended Bundle of Optical Fibers

MIT Develops New Optical Brush
A new imaging system developed at the MIT Media Lab uses an open-ended bundle of optical fibers — no lenses, protective housing needed. The fibers are connected to an array of photosensors at one end; the other ends can be left to wave free, so they could pass individually through micrometer-scale gaps in a porous […]
