Discover the incredible distances of the furthest star, Earendel, and exoplanet, Hoth, from Earth. Learn how these discoveries were made using gravitational lensing and what makes them unique.
How far away is the furthest star? What about the furthest exoplanet? Learn just how far, and what makes these discoveries unique.Sign up for our email newsletter for the latest science news Faraway from Earth in the Sunrise Arc galaxy lies a star so distant that it took 12.9 billion years for its light to reach our planet. Named Earendel, after a character from J.R.R Tolkien’s, this star is the most distant ever observed by scientists and is now a mind-boggling 28 billion light years from Earth.
“The extra boost from the gravitational lensing has been really exciting to be able to sort of peer inside one of these galaxies and see down to the level of these individual stars,” Welch says.Following Earendel’s discovery, researchers have used the James Webb Space Telescope to continue parsing out details. The star is a massive B-type star, around 50 times the size of our own sun and likely about twice as hot.
“Typically, when we see stars that massive in the nearby universe, they have companions,” he explains. “When we got the data, it turned out that was exactly what we saw. really clear signatures of two components.” Researchers have thus far discovered around 5,000 weird and wonderful exoplanets. Kepler-7b for example, is a large, hot version of our own solar system’s Jupiter. The first exoplanet to have its cloud system mapped, researchers made the startling discovery that it has the

Canada Rare Earth Secures 70% Stake in Laos Rare Earth RefineryCanada Rare Earth announced it has signed a Memorandum of Understanding with a Laotian company to purchase 70% of a fully permitted rare earth refinery. The refinery, with a capacity of 3,000 tonnes per year, was built 12 years ago but has remained idle due to policy changes. The Lao government is now supporting the refinery's operation and encouraging in-country processing of rare earth concentrates. The refinery is expected to be operational in Q4 2025 after minor refurbishments.

Musk to Lead DOGE in Trump White House, Aimed at Slashing Trillions from Federal BudgetElon Musk, alongside co-chairman Vivek Ramaswamy, will head the DOGE initiative in the incoming Trump administration. DOGE aims to reduce waste, eliminate redundant agencies, and improve government efficiency. Musk, known for his SpaceX ventures and significant political donations to Trump's campaign, is projected to use the Eisenhower Executive Office Building for his operations. The arrangement raises ethical questions and uncertainties regarding Musk's access level and Ramaswamy's office space. DOGE, operating outside of official government structures, seeks to cut $2 trillion from the federal budget, though Musk acknowledges the achievable target might be closer to $1 trillion. He views the government as ripe for cuts, stating it's 'like being in a room full of targets'.
