VICTORIA, Seychelles--(BUSINESS WIRE)--May 25, 2023--

Scientists have spent 20 years putting together time-lapse footage offering a stunning window into the past. Two decades of data taken from NASA’s Chandra X-ray Observatory were used by astronomers to create a video of a stellar eruption that actually occurred 180 years ago. Observations from Chandra, taken in 1999, 2003, 2009, 2014 and 2020 were all used, in combination with data from ESA’s XMM-Newton spacecraft. With the combined data, experts were able to capture the stellar explosion, known as Eta Carinae. Eta Carinae is a famous star system containing two large stars, one of which is around 90 times larger than the Sun, while the other is around 30 times as large. The “Great Eruption” from Eta Carinae is believed to be the result of the merging of two stars that were originally part of a three-star system. Eta Carinae Time-Lapse, Chandra X-ray Observatory www.youtube.com It first took place in the mid-19th century and the aftermath is still continuing to be observed today. New footage shows how the explosion has expanded into space with staggering speeds of up to 4.5 million miles per hour. In a statement, NASA officials explained: “During this event, Eta Carinae ejected between 10 and 45 times the mass of the sun. This material became a dense pair of spherical clouds of gas, now called the Homunculus Nebula, on opposite sides of the two stars.” The Homunculus Nebula is the blue cloud visible in the video, while the growing bright orange ring shows how X-ray emissions have grown and expanded over time. “The new movie of Chandra, plus a deep, summed image generated by adding the data together, reveal important hints about Eta Carinae’s volatile history,” the statement read. “This includes the rapid expansion of the ring, and a previously-unknown faint shell of X-rays outside it.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

SpaceX has broken its own record for the number of launches in a single year with its 62nd rocket sent into space on Sunday. A Falcon 9 carrying Starlink internet satellites lifted off from Nasa’s Kennedy Space Center in Cape Canaveral, Florida, at 10.47pm local time, surpassing the previous milestone of 61 launches set in 2022. It was the 10th flight for the first stage booster rocket, with SpaceX also breaking a separate record earlier this year for launching reused rockets. The Falcon 9 rocket landed on a drone ship in the Atlantic Ocean after delivering the Starlink satellites into low-Earth orbit. SpaceX boss Elon Musk said SpaceX could complete up to 100 rocket launches this year, making the private space firm by far the most prolific company or space agency to send payloads into space. “SpaceX has delivered ~80 per cent of all Earth payload mass to orbit in 2023. China is ~10 per cent and rest of world other ~10 per cent,” Mr Musk posted on X, formerly known as Twitter. “Based on the Falcon launch plan for next year, SpaceX will deliver ~90 per cent of all Earth payload to orbit. Starship will take that to >99 per cent in future years. These magnitudes are madness to consider, but necessary to make consciousness multiplanetary.” SpaceX’s Starship is the largest and most powerful rocket ever built – measuring 121 metres in height and with a thrust of 5,000 metric tons – but is yet to successfully complete an orbital flight. Following a successful high-altitude flight test in 2021, SpaceX attempted a 90 minute orbital flight earlier this year but it exploded just three minutes into the flight. The next attempt is expected to take place this month, though no exact date has been set. More than 1,000 design changes have been made to the craft since the first failed attempt, including new venting systems and heat shields to improve the stage separation of the upper and lower stages of the rocket. The US Federal Aviation Administration (FAA) is yet to grant a launch licence for the latest mission amid concerns about issues revealed in the first orbital launch attempt. SpaceX has already secured a multi-billion dollar deal with Nasa to keep developing Starship for use on the US space agency’s Artemis mission, which aims to return astronauts to the Moon this decade. Mr Musk has previously said that Starship is integral to his plans to turn humanity into a multi-planetary species, with the aim of deploying a fleet of Starships to establish a permanent colony on Mars before 2050.
