Using data provided by NASA/ESA’ Hubble Space Telescope, an international team of astronomers have discovered an amazing and rare exoplanet (a planet outside the solar system) with a giant comet-like tail.
This June, skywatchers will have an opportunity to observe in the western sky — less than an hour after sunset — the two brightest planets in the night sky, Venus the brightest planet, and Jupiter as they are going to converge for a jaw-dropping close encounter.
Using data provided by NASA’s Spitzer Telescope, astronomers suggests that our galaxy may be inhabited by thousands of hot Neptune-sized planets with clouds of helium, an exotic class of planets in our Milky Way galaxy.
The Huge space between galaxies is not completely empty, it is inhabited by some stars which were flung far away from any other galaxies or stars and lost forever in the dark region of intergalactic space. These stars lives in solitude far enough from their nearest neighbors.
Using NASA’ Hubble Telescope, astronomers have observed the Arches Cluster, the most dense cluster known in the Milky Way with a mass equivalent to more than 10,000 Sun-like stars in a space with a radius equal to the distance between the sun and its nearest neighbor Alpha Centauri star system.
In this image, released recently by ESA — European Space Agency — we can see a pronounced effect of prevailing wind on the red planet, Mars.
How do astronomers estimate the mass of the Milky Way galaxy? It seems like a simple question, but it is not. Our galaxy consists of roughly 100 billion stars, stretching up to 200,000 light years from edge to edge, wide enough to makes it very difficult to measure.
Astronomers from Massachusetts Institute of Technology (MIT) and Aarhus University (Denmark) have discovered 74 Earth-sized exoplanets — planets beyond our solar system orbiting a star other than the Sun — located hundreds of light years away from Earth, orbit their host stars in the same way that our planet orbits the sun, following similar circular orbital paths.
Using the Hubble Space Telescope, astronomers have investigated the relationship between monster black holes that power radio-signal-emitting galactic jets and galaxies that have undergone mergers.
