Astronomers observe a supernovae within hours of the explosion
For the first time ever, scientists have gathered direct evidence of a rare Wolf-Rayet star being linked to a specific type of stellar explosion known as a Type IIb supernova. Peter Nugent of the Lawrence Berkeley National Laboratory talks to us about this star:
We never had a nearby example where we could say, ‘oh this star became this supernova.’ So this was the first time we can directly point to it and say because we heated up this wind and because we could see the wind that looks just like a Wolf-Rayet star, we know that the Wolf-Rayet star blew up and then became this type of supernova.
Nugent says they caught this star – a whopping 360 million light years away – just a few hours after it exploded.
Caught a glimpse of a ‘shooting star’ (meteor) last eve and thought about our plan to book an interview with researchers involved in the first analysis of stardust that was collected during NASA’s Stardust Mission. The Berkeley Lab was one of the facilities that analyzed tiny specks of interstellar dust and found they are more complex in composition and structure than previously imagined.
The greatest weapon against stress is our ability to choose one thought over another.
We are editing an interview now with a UC San Francisco psychiatrist about their study suggesting that a healthy lifestyle - good diet, getting enough sleep and exercising - may buffer against stress-related cell aging. Attitude helps, too. And that reminded us of the James quote.
Anthropologists, linguists and enthnographers were among the first to adopt sound recording as a tool for research. Physicist Carl Haber of the Lawrence Berkeley National Laboratory developed technology to restore and preserve historic sound recordings, including California Native American languages, songs and stories that were recorded in the early 1900s on wax cylinders.
It’s not because things are difficult that we dare not venture. It’s because we dare not venture that they are difficult.Seneca
