Hubble detects exoplanet with glowing water atmosphere

2 August 2017 Astronomy Now

Scientists have discovered the strongest evidence to date for a stratosphere on a planet outside our solar system, or exoplanet. A stratosphere is a layer of atmosphere in which temperature increases with higher altitudes.

Possible exomoon signal found

29 July 2017 Keith Cooper

Strong hints have been found of a possible exomoon candidate orbiting a gas giant planet over 4,000 light years away in the constellation of Cygnus the Swan. Should the moon be confirmed later this year by the Hubble Space Telescope, it will be the first moon ever discovered around a planet beyond our Solar System.

Galactic David and Goliath

28 July 2017 Astronomy Now

The gravitational dance between two galaxies in our local neighbourhood has led to intriguing visual features in both as witnessed in this new NASA/ESA Hubble Space Telescope image. The tiny NGC 1510 and its colossal neighbour NGC 1512 are at the beginning of a lengthy merger, a crucial process in galaxy evolution.

Hubble pushed beyond limits to spot clumps of new stars in distant galaxy

10 July 2017 Astronomy Now

When it comes to the distant Universe, even the keen vision of NASA’s Hubble Space Telescope can only go so far. Teasing out finer details requires clever thinking and a little help from a cosmic alignment with a gravitational lens.

Hubble captures massive dead disc galaxy

25 June 2017 Astronomy Now

By combining the power of a “natural lens” in space with the capability of NASA’s Hubble Space Telescope, astronomers made a surprising discovery—the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang.

Hubble applauds waltzing dwarfs

11 June 2017 Astronomy Now

Italian astronomers using the Hubble Space Telescope have tracked the rhythmic movement of two brown dwarf stars across the sky.

Cosmic magnifying-glass effect captures Universe’s brightest galaxies

7 June 2017 Astronomy Now

Boosted by natural magnifying lenses in space, NASA’s Hubble Space Telescope has captured unique close-up views of the Universe’s brightest infrared galaxies, which are as much as 10,000 times more luminous than our Milky Way.

Hubble spots moon around third largest dwarf planet

18 May 2017 Astronomy Now

The combined power of three space observatories, including NASA’s Hubble Space Telescope, has helped astronomers uncover a moon orbiting the third largest dwarf planet, catalogued as 2007 OR10. The pair resides in the frigid outskirts of our solar system called the Kuiper Belt, a realm of icy debris left over from our solar system’s formation 4.6 billion years ago.

‘Warm Neptune’ has unexpectedly primitive atmosphere

15 May 2017 Astronomy Now

A study combining observations from NASA’s Hubble and Spitzer space telescopes reveals that the distant planet HAT-P-26b has a primitive atmosphere composed almost entirely of hydrogen and helium. Located about 437 light-years away, HAT-P-26b orbits a star roughly twice as old as the Sun.

Observatories combine to crack open the Crab Nebula

12 May 2017 Astronomy Now

Astronomers have produced a highly detailed image of the Crab Nebula, by combining data from telescopes spanning nearly the entire breadth of the electromagnetic spectrum, from radio waves to X-rays.
