More, bigger wildfires burning western U.S.

New research suggests that the trend could continue as climate change causes temperatures to rise and drought to become more severe in the coming decades.

New image of red nebula 7,300 light-years from Earth

In the middle of little-known nebula Gum 41, brilliant hot young stars are giving off energetic radiation that causes the surrounding hydrogen to glow red.

The artist's concept depicts Kepler-186f, the first validated Earth-size planet orbiting a distant star in the habitable zone—a range of distances from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that Earth-size planets exist in the habitable zone of other stars and signals a significant step closer to finding a world similar to Earth. The artistic concept of Kepler-186f is the result of scientists and artists collaborating to help imagine the appearance of these distant worlds. Art Credit: Danielle Futselaar.

First potentially habitable Earth-sized planet discovered

The first Earth-sized exoplanet orbiting within the habitable zone of another star has been confirmed. The new planet, dubbed Kepler-186f, was discovered using NASA’s Kepler telescope.

Cosmic slurp: Where a black hole swallows a star

Astronomers have identified galaxies where a central black hole just disrupted and ‘ate’ a star. It’s like a black hole putting up a sign that says: Here I am.

Unexpected teleconnections in noctilucent clouds

Researchers investigating “night-shining” clouds found something they weren’t even looking for: teleconnections in Earth’s atmosphere that stretch all the way from the North Pole to the South Pole and back again

A tetrad of lunar eclipses, next one October 8

Monday’s eclipse marks the beginning of a special eclipse series known as a tetrad – four total lunar eclipses in a row, with no partial eclipses in between. The next one is October 8.
