Was there an Ocean on Ceres?
Orbiting between Mars and Jupiter, Ceres was first discovered and classified as a planet in 1801. In the 1850s, it was considered one of the largest of the little worlds in the asteroid belt. Astronomers re-classified Ceres as a dwarf planet in 2006. Oddly enough, it is believed that little Ceres, a tiny world that’s […]
Object Visits From Beyond Solar System
NASA reported on October 26, 2017 that astronomers have been watching a small body that could be an asteroid, or perhaps a comet, apparently from beyond our solar system, from somewhere in interstellar space. If that is indeed the case, it would be the first interstellar asteroid or comet to be observed and confirmed. The object […]

First on its journey were Jupiter and Saturn and it is currently exploring interstellar space. Its twin spacecraft, Voyager 2, visited Uranus and Neptune and is now in the outermost layer of the heliosphere, called […]
Alien Seekers Report Repeated Radio Bursts
Breakthrough Listen – a global astronomical initiative to find signs of intelligent life in the universe, launched in 2015 by Internet investor Yuri Milner and cosmologist Stephen Hawking used the Green Bank Telescope in West Virginia to observe the bursts from the mysterious distant object known as FRB 121102.
Water on TRAPPIST 1 Planets?
Planets in the TRAPPIST-1 system An international team of astronomers used the Hubble Space Telescope to estimate whether there might be water on the seven earth-sized planets orbiting the nearby dwarf star TRAPPIST-1. The results suggest that the outer planets of the system might still harbor substantial amounts of water. This includes the three planets […]
