"We have found a gas-giant planet that is a virtual twin of a previously known planet, but it looks like the two objects formed in different ways," said Trent Dupuy, astronomer at the Gemini Observatory.
"While we've learned a lot about ocean viruses in recent decades, we know next to nothing about soil viruses," said Matt Sullivan, a professor of microbiology at Ohio State. "This work's viruses are so novel that they have doubled the total known viruses in the world."

Volcanic Epicenter of the Solar System --New Hotspot on Jupiter's Io, Site of the Monster Surt Volcano
In February 2001 an eruption from the Surt volcano on the Jupiter-facing hemisphere of Io, the volcanic epi-center of our solar system, occurred with an estimated output of 78,000 Gigawatts. By comparison, the 1992 eruption of Mt Etna, Sicily, was estimated at 12 Gigawatts. During its peak, observed by the WM Keck II Telescope on Hawaii, its output almost matched the eruptive power of all of Io’s active volcanoes combined.
A new, striking image from NASA's Chandra X-ray Observatory and Hubble Space Telescope shows the intact dust towers of the spectacular star-forming region known as the Pillars of Creation, which is located in the southern portion of the Eagle Nebula, next to a giant cloud of hot dust thought to have been scorched by the blast of a star that exploded, or went supernova. Astronomers speculate that the supernova's shock wave could have already reached the dusty towers, causing them to topple about 6,000 years ago. However, because light from this region takes 7,000 years to reach Earth, we won't be able to capture photos of the destruction for another millennium or so.
South Africa on Friday unveiled a super radio telescope, a first phase of what will be the world's largest telescope in a project to try to unravel the secrets of the universe. The 64-dish MeerKAT telescope in the remote and arid Karoo region of South Africa will be integrated into a multi-nation Square KilometerArray (SKA). When fully operational, the SKA telescope will be 50 times more powerful than any other telescope in the world.
"Cosmic Messengers" --Mystery Sources Detected of Ghost Particles from the Most Extreme Environments in the Cosmos
"A cosmic mystery of immense proportions, once seemingly on the verge of solution, has deepened and left astronomers and astrophysicists more baffled than ever. The crux ... is that the vast majority of the mass of the universe seems to be missing."
"We are Very Perplexed" --Gaia and Hubble Space-Telescope Findings May Reveal a 'New Physics of the Universe'
The combined new data from the Gaia and Hubble Space Telescope data are in serious conflict with the Cosmic Microwave Background data," said Planck team member George Efstathiou of the Kavli Institute for Cosmology in Cambridge. The results fuel the mismatch between measurements for the expansion rate of the nearby universe, and those of the distant, primeval universe—before stars and galaxies even existed.
Today's "Planet Earth Report" --Our Planet's Deep Hidden Oceans --"Where Did All the Water Come From?"
Water-bearing minerals reveal that Earth’s mantle could hold more water than all its oceans. Researchers now ask: Where did it all come from?
Gravitational Waves from Black Hole-Neutron Star Binaries --"Unveiling the Origin of the Universe and Its Fate"
"So far, people have focused on binary neutron stars as a way of measuring the Hubble constant with gravitational waves," says Salvatore Vitale, assistant professor of physics at MIT. "We've shown there is another type of gravitational wave source which so far has not been exploited as much: black holes and neutron stars spiraling together.
