X-ray detection sheds new light on Pluto

more »
Scientists using NASA's Chandra X-ray Observatory have made the first detections of X-rays from Pluto. These observations offer new insight into the space environment surrounding the largest and best-known object in the solar system's outermost regions.

Pluto 'paints' its largest moon red

more »
In June 2015, when the cameras on NASA's approaching New Horizons spacecraft first spotted the large reddish polar region on Pluto's largest moon, Charon, mission scientists knew two things: they'd never seen anything like it elsewhere in our solar system, and they couldn't wait to get the story behind it. Over the past year, the scientists think they've solved the mystery.

Astronomers shed light on different galaxy types

more »
Scientists have taken a critical step towards understanding why different types of galaxies exist throughout the Universe. The research, made possible by cutting-edge instrumentation, means that astronomers can now classify galaxies according to their physical properties rather than human interpretation of a galaxy's appearance.

Peculiar metals? Insulator or conductor

more »
The electronic energy states allowed by quantum mechanics determine whether a solid is an insulator or whether it conducts electric current as a metal. Researchers have now theoretically predicted a novel material whose energy states exhibit a hitherto unknown peculiarity.

New Product: "Easy Transfer"

more »

Graphenea is launching “Easy Transfer”: the easiest way to transfer monolayer graphene onto your substrate. We applied our extensive experience in growing and transferring high quality graphene films to let you experiment with any novel substrate by using Graphenea’s Easy Transfer.

Advantages of using Easy Transfer:

  • Receive high quality graphene ready to deposit onto your substrate
  • Available in 1 x 1 cm and 1 x 1 inch sizes
  • Forget about IP issues. You receive monolayer graphene films ready to be deposited on your substrate
  • Shorten lead-time, you can avoid sending us your substrate and speed up your lab research work
  • Compatible with your process: easier integration for special substrates and allows fine tuning of your substrate
  • Graphenea offers you an affordable way to work on your substrate: 1 x 1 cm units at 80 USD and 1 x 1 inch units at 120 USD

Why “Easy Transfer” makes it possible:

  • Avoids metal etching
  • Avoids hazardous chemical handling
  • Manipulation of thin film done at Graphenea
  • Bottom layer removed

The North and South Jupiter

more »
A wide, looping orbit brought Juno close to Jupiter on August 27. As the spacecraft swung around the giant planet's poles JunoCam acquired these premier direct polar views, a change from the usual nearly equatorial perspective of outbound spacecraft and the telescopes of planet Earth. The sunlit side of Jupiter's north polar region (left) was imaged about 125,000 kilometers from the cloud tops, two hours before Juno's closest approach. An hour after close approach the south polar region was captured from 94,500 kilometers away. Strikingly different from the alternating light-colored zones and darker belts girdling more familiar equatorial regions, the polar region clouds appear more convoluted and mottled by many clockwise and counterclockwise rotating storm systems. Another 35 close orbital flybys are planned during the Juno mission.

Astronomers observe star reborn in a flash

more »
Astronomers using Hubble have been able to study stellar evolution in real time. Over a period of 30 years dramatic increases in the temperature of the star SAO 244567 have been observed. Now the star is cooling again, having been reborn into an earlier phase of stellar evolution. This makes it the first reborn star to have been observed during both the heating and cooling stages of rebirth.
