(Space Fellowship) Solar Flare from a Sharper Sun

Solar active region AR2192 was the largest recorded sunspot group of the last 24 years. Before rotating off the Earth-facing side of the Sun at the end of October, it produced a whopping six energetic X-class flares. Its most intense flare was captured on October 24 in this stunning view from the orbiting Solar Dynamics Observatory. The scene is a color combination of images made at three different wavelengths of extreme ultraviolet light; 193 angstroms shown in blue, 171 angstroms in white, [...]

(Space Fellowship) Soyuz Rolls Out to Pad as Station Crew Prepares to Double in Size

A trio of new Expedition 42 crew members is in its final preparations before Sunday’s launch and six-hour ride aboard a Soyuz TMA-15M spacecraft to the International Space Station. The rocket with the Soyuz capsule rolled out to the launch pad Friday morning at the Baikonur Cosmodrome in Kazakhstan. Aboard the station, Expedition 42 commander Barry “Butch” Wilmore worked on a plant growth experiment and continued calibration tests of the station’s new 3D printer. He also took some tim [...]

(Discovery News) DNews: Is Another Planet Lurking Beyond Neptune?

Our solar system has a handful of bodies exhibiting some strange, highly elliptical orbits. Are they being pulled by a massive planet WAY out there beyond Neptune? Amy Shira Teitel examines what might be causing these objects to behave so oddly.

(Space Fellowship) Hubble Sees a Spiral in a Furnace

This Hubble image is a snapshot of NGC 986 — a barred spiral galaxy discovered in 1828 by James Dunlop. This close-up view of the galaxy was captured by Hubble’s Wide Field and Planetary Camera 2 (WFPC2). NGC 986 is found in the constellation of Fornax (The Furnace), located in the southern sky. NGC 986 is a bright, 11th-magnitude galaxy sitting around 56 million light-years away, and its golden center and barred swirling arms are clearly visible in this image. Barred spiral galaxie [...]

(Discovery News) Asteroid Early-Warning Strategies Report Released

A United Nations team has been deliberating over the years regarding the gathering and analysis of near-Earth object (NEO) data.

(Space Fellowship) M1: The Crab Nebula

The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous 18th century list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, debris from the death explosion of a massive star, witnessed by astronomers in the year 1054. This sharp, ground-based telescopic view uses narrowband data to track emission from ionized oxygen and hydrogen atoms (in blue and red) and explore the tangled filaments within the still expanding cloud. One of t [...]

(Space Fellowship) Soyuz Preps for Rollout as Station Crew Works Array of Science

A trio of new Expedition 42 crew members is in its final preparations before Sunday’s launch and six-hour ride aboard a Soyuz TMA-15M spacecraft to the International Space Station. The rocket with the Soyuz capsule attached will roll out to the launch pad Friday morning at the Baikonur Cosmodrome in Kazakhstan. Aboard the orbital laboratory, the current crew members, Commander Barry Wilmore and Flight Engineers Alexander Samokutyaev and Elena Serova, are working their scheduled task list of [...]

(ScienceDaily) How to estimate the magnetic field of an exoplanet

Scientists developed a new method which allows to estimate the magnetic field of a distant exoplanet, i.e., a planet, which is located outside the Solar system and orbits a different star. Moreover, they managed to estimate the value of the magnetic moment of the planet HD 209458b.

(Discovery News) Mystery of Exoplanet's Magnetic Field Unlocked

A strange flow of charged hydrogen atoms around an exoplanet turns out to be stellar winds from its parent star.

(ScienceDaily) It's filamentary: How galaxies evolve in the cosmic web

How do galaxies like our Milky Way form, and just how do they evolve? Are galaxies affected by their surrounding environment? Astronomers now propose some answers. The researchers highlight the role of the 'cosmic web' -- a large-scale web-like structure comprised of galaxies -- on the evolution of galaxies that took place in the distant universe, a few billion years after the Big Bang.
