Astronomers Unveil Potential for New Earth-Like Planet 146 Light-Years Away, But Surface Temperature May Be as Cold as -70C
In a groundbreaking discovery, an international team of scientists has found a planet that could potentially support life, located approximately 146 light-years from Earth. The newly discovered exoplanet, named HD 137010 b, is roughly the size of our own planet and orbits a sun-like star in the constellation of Hercules.
Orbiting its parent star every 355 days, HD 137010 b's distance from the star could lead to surface temperatures as low as -70C. To put this into perspective, Mars' average temperature is around -67C (-89F). The star itself is cooler and dimmer than our sun, suggesting that the planet may face harsh conditions.
The team's findings were made possible by data captured in 2017 by NASA's Kepler space telescope's extended mission, K2. Citizen scientists played a crucial role in the discovery when they first detected the faint signal of the transit event that revealed HD 137010 b.
"We were initially excited to find what we thought was a transiting planet," said Dr. Chelsea Huang, one of the researchers involved in the study. "But after triple-checking our results, it became clear that this truly is an exoplanet."
The team's excitement lies in the fact that HD 137010 b is relatively close to us - approximately 150 light-years away. This proximity makes it a prime target for future observations with advanced telescopes.
According to astrophysicist Dr. Sara Webb, who was not involved in the research, more data is needed to confirm the planet as a confirmed exoplanet. "We're talking about a gold standard of three detections," she said. "One transit detection is intriguing, but it's just one piece of the puzzle."
While HD 137010 b bears some resemblance to our own planet, Webb noted that it could also be a "super snowball" - a large, icy world with potential for significant amounts of water, much of which may be frozen.
In terms of travel, reaching this distant exoplanet would require tens of thousands, if not hundreds of thousands, of years at current speeds.
