Good Lawd! Mass of lone ‘dead star’ measured for the first time
Posted by Paul Battista in category: space
Astronomers have measured the mass of a lone white dwarf star for the first time. This type of smoldering stellar remnant is formed at the end of the lives of low-mass stars and will be what the sun leaves behind when it dies in around 5 billion years.
The Hubble Space Telescope measured the mass of a white dwarf designated LAWD 37, which burned out over 1 billion years ago. In the work, scientists used a phenomenon first predicted in 1915 by Albert Einstein called “gravitational lensing,” which involves the bending of light by objects of great mass. The team determined that LAWD 37 has a mass around 56% that of the sun. The finding confirms current theories of how these stellar remnants form and evolve. This particular white dwarf is well studied because it is relatively close to Earth at just 15 light-years away in the constellation of Musca.

Saturn’s moon Mimas may be a ‘stealth’ ocean world

If Mimas has an ocean, it represents a new class of small, ‘stealth’ ocean worlds with surfaces that do not betray the ocean’s existence.

Bill Gates says A.I. like ChatGPT is ‘every bit as important as the PC, as the internet’
Posted by Kelvin Dafiaghor in categories: internet, mapping, robotics/AI, space
Microsoft co-founder Bill Gates knows a thing or two about paradigm shifts, having played a key role in personal computers becoming a thing. Today, he believes, an equally important development is beginning with ChatGPT and similar artificial intelligence tools.
“A.I. is going to be debated as the hottest topic of 2023. And you know what? That’s appropriate. This is every bit as important as the PC, as the internet,” Gates recently told Forbes, adding that he now spends about 10% of his time talking with Microsoft teams about their product road maps, despite having been long retired and focused on philanthropy.
ChatGPT, of course, is the A.I. chatbot that’s been making waves with its ability to respond to typed questions with eerily human-like responses. Launched a few months ago, ChatGPT now attracts more than 100 million monthly active users, according to a research note published Wednesday by UBS. It easily reached 100 million faster than TikTok or Instagram, the bank’s analysts noted, adding, “In 20 years following the internet space, we cannot recall a faster ramp in a consumer internet app.”

Pretty powerful’: Indiana man captures rare ‘green comet
Posted by Dan Breeden in category: space
LaPORTE COUNTY, Ind. ( WGN) — In freezing temperatures in rural LaPorte County, Indiana, a skywatcher was able to capture the rare “green comet” passing by Earth for the first time in 50,000 years.
Space enthusiasts like Patrick Thompson have been talking about C/2022 E3 — more commonly known as the “green comet” — for the last couple of weeks. The comet was discovered only last year as part of a survey that monitors the solar system for moving objects with a wide-field survey camera.

In October 2015 Neil Turok, director of the Perimeter Institute for Theoretical Physics (PI) located in Waterloo, Canada opened the new season of the PI Public Lecture Series with a talk about the remarkable simplicity that underlies nature. Professor Turok, who was born in South Africa and now lives in Canada, discussed how this simplicity at the largest and tiniest scales of the Universe is pointing toward new avenues of research and revolutionary advances in technology.

Discovery of new ice may change our understanding of water
Posted by Saúl Morales Rodriguéz in categories: energy, space
Researchers at UCL and the University of Cambridge have discovered a new type of ice that more closely resembles liquid water than any other known ices and that may rewrite our understanding of water and its many anomalies.
The newly discovered ice is amorphous—that is, its molecules are in a disorganized form, not neatly ordered as they are in ordinary, crystalline ice. Amorphous ice, although rare on Earth, is the main type of ice found in space. That is because in the colder environment of space, ice does not have enough thermal energy to form crystals.
For the study, published in the journal Science, the research team used a process called ball milling, vigorously shaking ordinary ice together with steel balls in a jar cooled to-200 degrees Centigrade.
