Weather forecasts made for planets beyond our solar system

more »
Using sensitive observations from the Kepler space telescope, astronomers have uncovered evidence of daily weather cycles on six extra-solar planets seen to exhibit different phases. Such phase variations occur as different portions of these planets reflect light from their stars, similar to the way our own moon cycles though different phases. Among the findings are indications of cloudy mornings on four of them and hot, clear afternoons on two others.

Europa's mystery dark material could be sea salt, NASA research reveals

more »
NASA laboratory experiments suggest the dark material coating some geological features of Jupiter's moon Europa is likely sea salt from a subsurface ocean, discolored by exposure to radiation. The presence of sea salt on Europa's surface suggests the ocean is interacting with its rocky seafloor -- an important consideration in determining whether the icy moon could support life.

Astronomy: Delta Cephei has a hidden companion

more »
To measure distances in the Universe, astronomers use Cepheids, a family of variable stars whose luminosity varies with time. Their role as distance calibrators has brought them attention from researchers for more than a century. While it was thought that nearly everything was known about the prototype of Cepheids, named Delta Cephei, a team of researchers have now discovered that this star is not alone, but that it has a hidden companion.

The weakest magnetic field in the solar system

more »
Magnetic fields easily penetrate matter. Creating a space practically devoid of magnetic fields thus presents a great challenge. An international team of physicists has now developed a shielding that dampens low frequency magnetic fields more than a million-fold. Using this mechanism, they have created a space that boasts the weakest magnetic field of our solar system. The physicists now intend to carry out precision experiments there.

Galaxies, Stars and Nebulae series Like the fury of a raging sea, this bubbly ocean of glowing hydrogen, oxygen, and sulphur gas lies in the extremely massive and luminous molecular nebula Messier 17.
This Hubble photograph captures a small region within Messier 17 (M17), a hotbed of star formation. M17, also known as the Omega or Swan Nebula, is located about 5500 light-years away in the Sagittarius constellation.
Ultraviolet radiation is carving and heating the surfaces of cold hydrogen gas clouds and the warmed surfaces glow orange and red. The intense heat and pressure causes some material to stream away from the surface, creating the glowing veil of even hotter green-coloured gas that masks background structures. The colours in the image represent various gases. Red represents sulphur; green, hydrogen; and blue, oxygen.

More evidence that the Milky Way has four spiral arms

more »
Astronomers have been arguing over just how many spiral arms our galaxy exhibits. Is the Milky Way a four or two-armed spiral galaxy? Astronomers had often assumed the Milky Way was potentially a four-armed spiral galaxy, but comparatively recent observations from NASA's Spitzer telescope implied the galaxy had two spiral arms. In 2013, astronomers mapped star forming regions and argued they had found the two missing arms, bringing the total number of arms back to four.

A new image of two tangled galaxies has been released by NASA's Great Observatories. The Antennae galaxies, located about 62 million light-years from Earth, are shown in this composite image from the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red). The Antennae galaxies take their name from the long, antenna-like arms seen in wide-angle views of the system. These features were produced in the collision.
