Host star is the brightest star with multiple known transiting Earth-size exoplanets. Another transiting planet in the system is suspected. [40] HD 101581 c: 0.0925 6.21 transit 41.7 0.740 ± 0.087 4675 ± 53 Host star is the brightest star with multiple known transiting Earth-size exoplanets. Another transiting planet in the system is ...
Explore the universe with news on fascinating discoveries, scientific advancements and more. The Curiosity rover has made its most unusual find to date on Mars: rocks made of pure sulfur.
The architecture involved multiple missions launching from Earth to Mars to collect the samples, and then conducting the first rocket launch from the surface of another planet to return the ...
The exoplanets were found using a statistical technique called "verification by multiplicity". 95% of the discovered exoplanets were smaller than Neptune and four, including Kepler-296f, were less than 2 1/2 the size of Earth and were in habitable zones where surface temperatures are suitable for liquid water.

The distance between Mars and the Earth will reach a remarkable new minimum of 55,651,582.118 km. It will be a slightly closer encounter by perihelic opposition (by 37,000 km) than the previous one of August 28, 2287. [73] The following closer encounter will be on September 8, 2729. 2655/2656 Triple conjunction Jupiter-Saturn 2663 Triple ...
NASA's Curiosity rover has been exploring the Gale Crater on Mars since 2012, and in that time has come up with some astounding discoveries that suggest the Red Planet was somewhat Earth-like in ...
The planets in the Kepler-444 system have radii of 0.4, 0.497, 0.53, 0.546 and 0.741 Earth radii, respectively. Due to their size and proximity to Kepler-444, these must be rocky planets, with masses close to that of Mars. For comparison, Mars has a mass of 0.105 Earth masses and a radius of 0.53 Earth radii. System with largest total planetary ...
The tiny moon is drawing closer to Mars at a rate of 6 feet (1.8 meters) every 100 years, and it will either crash into Mars in 50 million years or break up and become a ring around the planet.
