Hubble Views Two Spiral Galaxies Engaged in a “Cosmic Tug-of-War”

July 28, 2014

0 Comments

This newly released Hubble image shows two spiral galaxies engaged in a cosmic tug-of-war. From objects as small as Newton’s apple to those as large as a galaxy, no physical body is free from the stern bonds of gravity, as evidenced in this stunning picture captured by the Wide Field Camera 3 and Advanced Camera […]

The Search for Variable Stars in Globular Cluster M4

July 25, 2014

0 Comments

In a newly published study, astronomers detail the results of a photometric search for variable stars in the core of the globular cluster M4. A globular cluster is a roughly spherical ensemble of stars, as many as several million of them, gravitationally bound together in groups whose diameters can be as small as only tens […]

Astronomers Map Galaxy Cluster More Precisely Than Ever Before

July 25, 2014

0 Comments

Astronomers used almost 200 images of distant galaxies combined with Hubble data to measure the total mass of galaxy cluster MCS J0416.1–2403 more precisely than ever before. Astronomers using the NASA/ESA Hubble Space Telescope have mapped the mass within a galaxy cluster more precisely than ever before. Created using observations from Hubble’s Frontier Fields observing […]

New Images and 3D Model of Comet 67P

July 25, 2014

0 Comments

New images from ESA’s Rosetta spacecraft reveal surface structures of comet 67P/Churyumov-Gerasimenko, allowing scientists to create a 3D shape model of the nucleus. As the European Space Agency’s Rosetta probe approaches Comet 67P/Churyumov-Gerasimenko (67P) for an August rendezvous, the comet’s core is coming into sharper focus. Today, ESA released a new set of images and […]

Most Precise Measurement Ever of the Radius of a Planet Outside Our Solar System

July 24, 2014

0 Comments

Scientists have made most precise measurement ever of the radius of a planet outside our solar system, confirming Kepler-93b as a “super-Earth” that is about one-and-a-half times the size of our planet. Thanks to NASA’s Kepler and Spitzer Space Telescopes, scientists have made the most precise measurement ever of the radius of a planet outside […]

Hubble Reveals That Three Hot Jupiters Are Surprisingly Dry

July 24, 2014

0 Comments

Using the Hubble Space Telescope, astronomers reveal that three exoplanets that were thought to be ideal candidates for detecting water vapor in their atmospheres contain far less water than predicted by standard planet-formation theories. Astronomers using NASA’s Hubble Space Telescope have gone looking for water vapor in the atmospheres of three planets orbiting stars similar […]

A New Approach in the Search for Extraterrestrial Intelligence

July 23, 2014

0 Comments

Scientists are taking a new approach in the search for extraterrestrial intelligence, studying exoplanet atmospheres for signs of pollution. Cambridge, Massachusetts – Humanity is on the threshold of being able to detect signs of alien life on other worlds. By studying exoplanet atmospheres, we can look for gases like oxygen and methane that only coexist […]

No New Cosmological Concordance with Massive Sterile Neutrinos

July 23, 2014

0 Comments

A newly published study shows that modifying the standard cosmological model in order to include fairly massive neutrinos does not explain all the physical observations simultaneously. Neutrinos, also known as ‘ghost particles’ because they barely interact with other particles or their surroundings, are massless particles according to the standard model of particle physics. However, there […]
