The technology is powered by LaMDA, a large language model Google unveiled in May 2021. On Monday, Pichai unveiled its Bard AI service in a blog post on Google's website, which he described as "an experimental conversational AI service." Bard is powered by LaMDA, a language model trained on dialogue that Google announced in May 2021. Pichai noted that Bard will draw on information from the web to provide "fresh, high-quality responses." However, Pichai noted that Google is releasing Bard with a "lightweight model version of LaMDA."

☆ Explainer: What to expect during the green comet's encounter with Earth
▼ + stars: | 2023-01-30 | by ( Joey Roulette | ) www.reuters.com time to read: +3 min

Nicknamed "dirty snowballs" by astronomers, comets are balls of ice, dust and rocks that typically hail from the ring of icy material called the Oort cloud at our solar system's outer edge. One known comet actually originated outside the solar system - 2I/Borisov. Comets are composed of a solid core of rock, ice and dust and are blanketed by a thin and gassy atmosphere of more ice and dust, called a coma. Its greenish, emerald hue reflects the comet's chemical composition - it is the result of a clash between sunlight and carbon-based molecules in the comet's coma. NASA plans to observe the comet with its James Webb Space Telescope (JWST), which could provide clues about the solar system's formation.

☆ How exoplanet hunters find alien worlds hundreds of light-years away and figure out if they have water
▼ + stars: | 2023-01-12 | by ( Paola Rosa-Aquino | ) www.businessinsider.com time to read: +6 min

In the journal Nature Astronomy, astronomers announced that the two exoplanets — Kepler-138 c and Kepler-138 d — could be made up of mostly water. NASA AmesSince the first worlds outside our solar system were discovered in 1992, astronomers have searched for other planets orbiting sun-like stars. Astronomers have already captured direct evidence of 5,241 planets beyond our solar system, according to NASA's Exoplanet Archive. Water worlds beyond our solar system could be abundant in the universeWorlds rich in liquid water might not be as rare as astronomers previously thought, Piaulet said. But by discovering and studying new worlds, astronomers can hone in on what makes a world habitable beyond a sample size of one — Earth.

There's a new heavy hitter in the hunt for planets beyond our solar system. NASA’s James Webb Space Telescope — the next-generation observatory that has already beamed back some of the clearest and most stunning views of the universe — was used for the first time to confirm the existence of an exoplanet, scientists announced Wednesday. The exoplanet confirmation marks an important milestone for the $10 billion Webb telescope, which launched into space in December 2021 and began science operations less than a year ago. “These first observational results from an Earth-size, rocky planet open the door to many future possibilities for studying rocky planet atmospheres with Webb,” Mark Clampin, director of the astrophysics division at NASA headquarters in Washington, D.C., said in a statement. “Webb is bringing us closer and closer to a new understanding of Earth-like worlds outside our solar system, and the mission is only just getting started.”

The first full-color image released from the next-generation James Webb Space Telescope is the sharpest infrared image of the distant universe ever produced, according to NASA. Space Telescope Science Institut / NASA, ESA, CSA, STScI, Webb ERONASA released the first batch of images from the tennis court-sized observatory to much fanfare in July.

CNN —The James Webb Space Telescope has captured a unique perspective of the universe, including never-before-seen galaxies that glitter like diamonds in the cosmos. “I was blown away by the first PEARLS images,” said study coauthor Rolf Jansen, research scientist at Arizona State University and a PEARLS coinvestigator, in a statement. Together, the wavelengths of light from both telescopes reveal unprecedented depth and detail of a wealth of galaxies in the universe. The image represents just a portion of the full PEARLS field, which will be about four times larger. Other pinpricks of light in the image represent a range of stars in our Milky Way galaxy.

☆ Astronauts explain why nobody has visited the moon in 50 years — and the reasons are depressing

The last time a person visited the moon was in December 1972, during NASA's Apollo 17 mission. But those stays during the Apollo program didn't establish a lasting human presence on the moon. Researchers and entrepreneurs have long pushed for the creation of a crewed base on the moon — a lunar space station. But many astronauts and other experts suggest the biggest impediments to making new crewed moon missions a reality are banal and somewhat depressing. During NASA's Apollo program, 12 people landed on the moon.

The gamma-ray burst, called GRB 211211A, lasted about a minute. Gamma-ray bursts are considered among the strongest and brightest explosions in the universe, and they can range from a few milliseconds to several hours in length. An artist's illustration of GRB 211211A shows the kilonova and gamma-ray burst (right) and ejected material from the explosion (left). After determining that a kilonova created the infrared light, astronomers grew even more puzzled by the gamma-ray burst’s duration. Gamma-ray bursts caused by these rare explosions have only ever been observed to last less than two seconds, but this signal lasted for at least one minute.

CNN —The James Webb Space Telescope has spied clouds on one of the solar system’s most intriguing moons. Titan’s atmosphere is made of nitrogen and methane, which gives it a fuzzy, orange appearance. Astronomers compared Webb (left) and Keck images of Titan to see how clouds evolved. The data, which is still being analyzed, was able to see deeper into Titan’s atmosphere and surface than the Cassini spacecraft, which orbited Saturn and its moons for 13 years. The cloud observations were a long time coming.

CNN —The beautiful chaos of two merging galaxies shines in the latest image captured by the James Webb Space Telescope. The Webb telescope, designed to observe faint, distant galaxies and other worlds, is an international mission between NASA and its partners, the European Space Agency and Canadian Space Agency. The pair of galaxies, known as II ZW 96, are located some 500 million light-years from Earth in the Delphinus constellation. Astronomers are using the observatory to study how galaxies evolve and, among other topics, why luminous infrared galaxies like II ZW 96 shine brightly in infrared light, reaching luminosities more than 100 billion times that of our sun. Researchers have turned Webb’s instruments on merging galaxies, including II ZW 96, to pick out fine details and compare the images with those previously taken by ground-based telescopes and the Hubble Space Telescope.

CNN —Despite numerous calls from astronomers to rename its powerful new telescope, NASA officials stood by the naming of the James Webb Space Telescope before its launch. With the telescope nearly a year into its stint in space, the agency has released its chief historian’s investigation into the namesake of the telescope. Earlier this summer, Dr. Jane Rigby, the operations project scientist for the James Webb Space Telescope, tweeted that “a transformative telescope should have a name that stands for discovery and inclusion.”Officials at NASA have refused to rename it, though, citing an investigation into Webb’s career. The James Webb Space Telescope is the most powerful telescope ever built. NASA Goddard Space Flight CenterNo evidence links Webb to any action that followed those discussions, Odom said.

CNN —The cosmic chaos caused by a very young star has been captured in the latest enchanting image from NASA’s James Webb Space Telescope. The protostar the image centers around is hidden from view in the neck of a dark, hourglass-shape cloud of gas and dust. The thicker the layer of dust, the less blue light is able to escape, creating pockets of orange. As a result, the protostar dominates the space, taking much of the material for itself,” according to the news release. Webb, which first began sharing new perspectives on the universe in July, is an international partnership between NASA, the European Space Agency and the Canadian Space Agency.

In fact, it kind of looks like a comet now, NASA discovered when the Hubble Space Telescope snapped a new image of the distant space rock. So on September 26, the DART spacecraft slammed into Dimorphos, pushing it slightly closer to the larger asteroid it's orbiting, called Didymos. Telescopes across the planet and throughout Earth's orbit, including the new James Webb Space Telescope, are watching the asteroid closely.
