World’s most heat resistant spacecraft

World’s most heat resistant spacecraft

Scientists have identified materials that can withstand temperatures of nearly 4,000 degrees Celsius. This is an advance that may pave the way for improved heat resistant shielding for the faster-than-ever hypersonic space vehicles. Researchers from Imperial College London in the UK discovered that the melting point of hafnium carbide is the highest ever recorded for a material.  The researchers developed a new extreme heating technique using lasers to test the heat tolerance of TaC and…

‘Einstein Ring’ seen in galaxy 12 billion light-years away

The Huffington Post: A brilliant “ring of fire” has been spotted in deep space, giving astronomers a rare glimpse of a galaxy 12 billion light-years away. The  “Einstein ring” was captured at a super-high resolution of 23 milliarcseconds by the  a ground telescope in the Atacama desert in Northern Chile. “With the astounding level of detail in these new ALMA images, astronomers will now be able to reassemble the information contained in the distorted image we see as a…
