Study explains strength gap between graphene, carbon fiber

more »
Carbon fiber, a pillar of strength in materials manufacturing for decades, isn't as good as it could be, but there are ways to improve it, according to scientists. They found the polymer chains that make up a common carbon fiber are prone to misalign during manufacture, a defect the researchers compared with a faulty zipper that weakens the product.

ExoMars orbiter reaches Mars orbit while lander situation under assessment

more »
The Trace Gas Orbiter (TGO) of ESA's ExoMars 2016 has successfully performed the long 139-minute burn required to be captured by Mars and entered an elliptical orbit around the Red Planet, while contact has not yet been confirmed with the mission's test lander from the surface.

Unexplainable activity in distant stars: New class of explosive events?

more »
Researcher pored through more than 10 years of existing Chandra X-ray Observatory data and found stars that repeatedly survive quick, massive surges in space energy. There are no such instances in our galaxy, as stars are destroyed by similar conditions.

Astrophysicists map the Milky Way

more »
Hydrogen. Atomic number 1. It is the simplest and lightest element on the periodic table, but don't be fooled by its humble appearance. With just a single proton and a single electron, it is the most abundant element in the universe and has fueled star formation for the past 13 billion years. Now scientists have mapped the key ingredient's distribution across the Milky Way, revealing details about our galaxy that have never been seen before.

First Pluto, now this: Discovery of first binary-binary calls solar system formation into question

more »
Everything we know about the formation of solar systems might be wrong, says two astronomers. They've discovered the first "binary--binary" -- two massive companions around one star in a close binary system, one so-called giant planet and one brown dwarf, or "failed star" The first, called MARVELS-7a, is 12 times the mass of Jupiter, while the second, MARVELS-7b, has 57 times the mass of Jupiter.

The Tulip in the Swan

more »
Framing a bright emission region this telescopic view looks out along the plane of our Milky Way Galaxy toward the nebula rich constellation Cygnus the Swan. Popularly called the Tulip Nebula, the glowing cloud of interstellar gas and dust is also found in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101. About 8,000 light-years distant and 70 light-years across the complex and beautiful nebula blossoms at the center of the composite image. Red, green, and blue hues map emission from ionized sulfur, hydrogen, and oxygen atoms. Ultraviolet radiation from young, energetic stars at the edge of the Cygnus OB3 association, including O star HDE 227018, ionizes the atoms and powers the visible light emission from the Tulip Nebula. HDE 227018 is the bright star very near the blue arc at the center of the cosmic tulip.

No Signal From Mars Lander, but European Officials Declare Mission a Success

more »
The lack of a signal most likely means the planned “soft landing” failed, but the orbiter continues to gather and transmit data.
