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 […]

New measurements by NASA’s Fermi Gamma-ray Space Telescope reveal a binary star system whose pulsar switched from radio emissions to high-energy gamma rays. Zoom into an artist’s concept of AY Sextantis, a binary star system whose pulsar switched from radio emissions to high-energy gamma rays in 2013. This transition likely means the pulsar’s spin-up process […]

NASA Discovers Further Evidence of Dry Ice Gullies on Mars

July 11, 2014

0 Comments

A new study details further evidence of dry ice gullies on Mars, revealing that the gullies on Mars’ surface are primarily formed by the seasonal freezing of carbon dioxide, not liquid water. Repeated high-resolution observations made by NASA’s Mars Reconnaissance Orbiter (MRO) indicate the gullies on Mars’ surface are primarily formed by the seasonal freezing […]

New Data from another “tsunami wave” generated by our sun confirms that NASA’s Voyager 1 spacecraft is in interstellar space. NASA’s Voyager 1 spacecraft has experienced a new “tsunami wave” from the sun as it sails through interstellar space. Such waves are what led scientists to the conclusion, in the fall of 2013, that Voyager […]

Astronomers Create First Full 3D Model of Eta Carinae Nebula

July 8, 2014

1 Comment

Using new data from the European Southern Observatory’s Very Large Telescope and its X-Shooter spectrograph, astronomers have created the first full 3D model of Eta Carinae Nebula. In the middle of the 19th century, the massive binary system Eta Carinae underwent an eruption that ejected at least 10 times the sun’s mass and made it […]
