The youngest exoplanet yet discovered is less than 1 million years old and orbits Coku Tau 4, a star 420 light-years away. Astronomers inferred the planet’s presence from an enormous hole in the dusty disk that girdles the star. The hole is 10 times the size of Earth’s orbit around the Sun and probably caused […]
Liquid water may still flow on Mars, but that doesn’t mean it’s easy to spot. The search for water on the Red Planet has taken more than 15 years to turn up definitive signs that liquid flows on the surface today. In the past, however, rivers and oceans may have covered the land. Where did […]
New Horizons space probe provides the highest resolution image of Pluto ever seen as presented in a NASA press conference on July 15, 2015, at the Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland. This region near Pluto’s equator surprisingly contains a range of youthful mountains rising to heights of 11,000 feet (3,500 m) above […]
Astronomers have discovered a pair of neighboring planets with dissimilar densities orbiting very close to each other. original
by Nola Taylor Redd , Space.com Contributor | January 22, 2016 01:06pm ET This artist’s impression shows the distant dwarf planet Eris in the distance with its moon Dysmonia in the foreground. New observations have shown that Eris is smaller than previously thought and almost exactly the same size as Pluto. Eris is extremely reflective […]

130mm Aperture Newtonian Reflector Telescope with SkyAlign Go-To ComputerCredit: Space.com Reflector Telescopes: Newton Astride a Tripod Bright guy, Sir Isaac Newton: He managed to distill the mechanics of our local universe down to three simple laws of motion. He developed much of mathematical calculus. And he harnessed the magnification properties of concave mirrors to drive […]
by Karl Tate , SPACE.com Infographics Artist | September 11, 2015 09:29am ET Editor’s note: The next solar eclipse will occur on Sunday, Sept. 13, 2015. It will be a partial solar eclipse that will be visible primarily from South Africa and Antarctica. The next lunar eclipse will be a total lunar eclipse on Sept. […]
Since science operations began in May 2009, the Kepler team has released two catalogs of transiting planet candidates. original
This artist’s concept depicts an itsy bitsy planetary system – so compact, in fact, that it’s more like Jupiter and its moons than a star and its planets. Astronomers using data from NASA’s Kepler mission and ground-based telescopes recently confirmed that the system, KOI-961, hosts the three smallest exoplanets known so far to orbit a […]

Editor’s note: The next lunar eclipse will be a total lunar eclipse on Sept. 27, 2015. It will occur while the moon is at perigee, making it a rare Supermoon Blood Moon lunar eclipse . Such an event won’t happen again until 2033. A total lunar eclipse occurs when the moon passes completely beneath Earth’s […]
