Google employees reportedly bashed Bard before launch

Google is no stranger to controversy, and the launch of its AI-powered chatbot, Bard, was no exception. According to recent reports, several Google employees expressed concerns about the chatbot's capabilities. Moreover, employees were concerned about the potential impact on the company's reputation before its launch. Google designed Bard to simulate a human-like conversation and provide users with information and recommendations. The engineers trained the chatbot on a massive dataset of text from various sources, including books, websites, and conversations. Google touted Bard as a breakthrough in AI and a major step forward in natural language processing. However, as the launch date approached, some Google employees reportedly expressed doubts about Bard's ability to deliver on it...

A defunct NASA spacecraft returns to Earth after 21 years

After 21 years of orbiting in space, a defunct NASA spacecraft has finally made its way back to Earth. The spacecraft called the Compton Gamma Ray Observatory (CGRO), was a groundbreaking mission. It helped scientists study the high-energy universe and discover some of the most mysterious objects in the cosmos. Its return to Earth marks the end of an era of space exploration. This return also presents a unique opportunity for researchers to study the effects of long-term spaceflight on hardware. The CGRO was the second of NASA's Great Observatories. NASA launched CGRO on April 5, 1991. It consisted of a series of four space telescopes that aimed to study the universe in different wavelengths of light. The CGRO was designed to detect gamma rays, the most energetic form of light. It can ...

SpaceX giant rocket exploded minutes after launch from Texas

In March 2021, SpaceX, the private space exploration company founded by Elon Musk, suffered a setback when its prototype Starship SN11 rocket exploded minutes after launch from a test facility in Boca Chica, Texas. The rocket's test flight was progressing towards achieving SpaceX's goal of developing a fully reusable spacecraft capable of carrying people and cargo to the Moon, Mars, and beyond when the incident occurred. SpaceX designed the SN11 rocket, a stainless-steel prototype that stood at around 120 feet tall. To be a critical component of the Starship program. A venture that seeks to replace all of its current spacecraft and launch vehicles with a single, reusable system. Three Raptor engines, the same type that will be used on the operational Starship spacecraft, powered the...

Astronomers Just Found a Radio Galaxy That Turned Into a Blazar

A team of astronomers has made a fascinating discovery in the universe. They find a radio galaxy that has turned into a blazar. This discovery is significant because it helps us understand how these mysterious objects in space can change over time. Supermassive black holes at the center of galaxies power two types of active galactic nuclei (AGN): radio galaxies and blazars. The black hole emits jets of particles and radiation in a radio galaxy. Which travel out into space and produce radio emissions. The jets in a blazar aim directly at Earth, producing a bright source of radiation visible across the electromagnetic spectrum. Previously, scientists believed that radio galaxies could not transform into blazars due to the absence of directed jets toward Earth. However, the discovery o...

NASA names first woman, black astronauts for mission

NASA has named the first woman and the first African American ever assigned as astronauts to a lunar mission. Introducing them as part of the four-member team chosen to fly as early as next year. On what would be the first crewed voyage around the moon in more than 50 years. The US space agency NASA has announced the first crewed moon mission in five decades. For this historic Artemis II mission, the National Aeronautics and Space Administration (NASA) and the Canadian Space Agency (CSA) announced on Monday names of four astronauts.In a first, the American space agency has selected a woman Christina Koch and a Black man Victor Glover to voyage into deep space.Other two astronauts part of the crew are Reid Wiseman and Jeremy Hansen. Hansen is a Canadian Space Agency astronaut. The c...
