NASA’s Hubble Finds 2 Tiny Dwarf Galaxies

NASA’s Hubble Space Telescope has sent images of two tiny dwarf galaxies that have wandered from a vast cosmic wilderness into a nearby “big city” packed with galaxies, ahead of starting a firestorm of star birth. After being quiescent for billions of years, the galaxies, called Pisces A and B, are late bloomers because they have spent most of their ...

Hubble Locates a New Gem in Space

The Hubble Space Telescope (HST), which is running its 25th year in the space currently, spotted a little gem – a planetary nebula, there. The planetary nebula known as “NGC 6818” or “Little Gem Nebula” is an intergalactic cloud of dust, helium, hydrogen and many other ionized gases. It is situated in the constellation of Sagittarius also called “The Archer”, ...

Distant Uranus-sized exoplanet discovered through microlensing

NASA’s Hubble Space Telescope and the W.M. Keck Observatory in Hawaii have made independent confirmations of an exoplanet orbiting far from its central star, using a technique called gravitational microlensing. The technique helps find exoplanets far from their central stars as Jupiter and Saturn are from our sun, revealed two papers published in the July 30 edition of the Astrophysical ...

India’s Astrosat to Join NASA’s Hubble, Russian Spektr R, Japan’s Suzaku to Study Astronomy

India is gearing up to launch its own ASTROSAT, the first dedicated space observatory similar to NASA’s Hubble to study deep space in October 2015. The observatory to be placed in equatorial range for five years will orbit around Earth at 650-km speed, said the Indian Space Research Organisation on Tuesday. Built by Bangalore-based ISRO Satellite Centre (ISAC), India hopes ...

NASA spy telescopes from NRO to decode mysterious dark energy

The US space agency is planning to use two former spy telescopes to study mysterious dark energy in space. NASA received the two telescopes from the National Reconnaissance Office (() intelligence agency. They were originally intended for the “Future Imaginary Architecture” programme aimed at creating a new generation of reconnaissance satellites for US intelligence. The spy telescopes given to NASA ...

Dark Matter darker than previously thought, say astronomers

Using observations from NASA’s Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark matter does not slow down when colliding with itself, meaning it interacts with itself less than previously thought. This finding narrows down the options for what this mysterious substance might be. “Dark matter is an enigma we have long sought to unravel. With the ...

NASA Hubble Telescope Picks ‘ghost light’ from Dead Galaxies

NASA’s Hubble telescope has picked up the faint, “ghost light” emanating from stars, which were supposedly ejected from ancient galaxies after they were gravitationally ripped apart billions of years ago. By observing the light from the orphaned or dead stars, astronomers have assembled forensic evidence that suggests as many as six galaxies were torn to pieces inside the cluster over ...
