Until this year, reports NPR, the world had recorded 1,640 deaths from Ebola since the virus was discovered in 1976. But so far this year, 887 people have died of Ebola in West Africa, the World Health Organization said Monday. And the outbreak is still spreading at a frightening rate. Last week, there were more than 200 new cases reported across four countries.

“We’re using Robo-AO’s extreme efficiency to survey in exquisite detail all of the candidate exoplanet host stars that have been discovered by NASA’s Kepler mission,” said Dr. Christoph Baranec of the University of Hawaii at Manoa’s Institute for Astronomy. “While Kepler has an unrivaled ability to discover exoplanets that pass between us and their host star, it comes at the price of reduced image quality, and that’s where Robo-AO excels.”

After a decade in space and 4 billion miles, Europe's Rosetta spacecraft has made history: For the first time ever, a robotic probe from Earth is flying with a comet and will soon enter orbit. The European Space Agency's Rosetta spacecraft arrived at its target, Comet 67P/Churyumov-Gerasimenko, today (Aug. 6) to end a 10-year journey across the solar system. The spacecraft performed an engine burn that brought it about 62 miles (100 kilometers) from the comet's surface.

During the middle of 2013, Jupiter’s moon Io came alive with volcanism. Now, an image from the Gemini Observatory captures what is one of the brightest volcanoes ever seen in our solar system. The image below, obtained on August 29, 2013, reveals the magnitude of the eruption that was the “grand finale” in a series of eruptions on the distant moon. Io’s volcanism is caused by the tidal push-and-pull of massive Jupiter, which heats the satellite’s interior – making it our Solar System’s most volcanically active known body.

"We're coming to our first taste of a geological unit that's part of the base of the mountain rather than the floor of the crater," said Curiosity Project Scientist John Grotzinger of the California Institute of Technology, Pasadena. "We will cross a major terrain boundary."

"Our part of the Milky Way is ringing like a bell," said Brian Yanny, of the Department of Energy’s Fermilab. "But we have not been able to identify the celestial object that passed through the Milky Way. It could have been one of the small satellite galaxies that move around the center of our galaxy, or an invisible structure such as a dark matter halo."

Last year, the Planck Telescope revealed the most detailed picture of the cosmic microwave background, the relic radiation from the Big Bang. But this map contains features that challenge the standard model of cosmology, the theory that describes our entire Universe from early on. Who is right, the map or the theory?

In 2011, an analysis of data from a NASA Fermi Gamma-Ray Space Telescope turned up massive, previously unseen galactic structures. A group of astrophysicists located two towering bubbles of plasma, now know as "Fermi Bubbles," each extending tens of thousands of light-years, emitting high-energy radiation above and below the plane of the galaxy. The structure spans more than half of the visible sky, from the constellation Virgo to the constellation Grus, and it may be millions of years old.

Russian scientists will focus on Moon and Mars exploration and repeat the Phobos-Grunt mission in the next decade, Space Research Institute Director Lev Zeleny said on Saturday. “The Moon and Mars are our priority for 2016-2025,” he said at the 40th COSPAR Scientific Assembly underway in Moscow on August 2-10.

Astronomers have long known that interstellar molecules containing carbon atoms exist and that by their nature they will absorb light shining on them from stars and other luminous bodies. Because of this, a number of scientists have previously proposed that some type of interstellar molecules are the source of diffuse interstellar bands -- the hundreds of dark absorption lines seen in color spectrograms taken from Earth.
