Kepler-64b: A spheroidal planet in a four-star system.

Have you ever wondered what it would be like to live on a planet that orbits two stars?It could have been our imagination to think, but until recently, it was thought to be something that only existed in the realm of science fiction. That is, until the discovery of Kepler-64b or PH1.

PH1 is the first reported case of a planet orbiting a double-star system, which is then orbited by a second pair of stars. This phenomenon is called a circumbinary planet in a four-star system. PH1 is a bit larger than Neptune and is thought to be a gas giant. It orbits its host stars every 137 days and is 900 times farther from its star than Earth is from our sun.

This planet’s discovery has been revolutionary for the astronomy community. The discovery of PH1 was made possible by volunteers from the Planet Hunters citizen science project. This project has allowed everyday citizens to contribute to cutting edge astronomical research and make amazing discoveries like PH1.

The planet's discovery has also been exciting for those of us who have always been fascinated with science fiction and what life on an alien planet may look like. PH1 is not Earth-like in any way but it does have similarities to other planets that we have discovered, such as its size being similar to Neptune.

The concept of a circumbinary planet in a four-star system has long been theorized but never observed—until now. This makes PH1 an incredibly interesting object for astronomers and space enthusiasts alike to study and learn more about.

What’s even more remarkable about this discovery is that it was made possible by everyday people who took part in the Planet Hunters project. This groundbreaking discovery shows that citizen science and collaboration can lead to amazing breakthroughs in astronomy and science as a whole.

James Webb Space Telescope Opens New Frontiers in the Search for Life Beyond Earth.

This image illustrates a science-based artist’s impression of K2-18 b, a potentially habitable exoplanet 120 light-years away, orbiting a cool dwarf star in its habitable zone. NASA’s James Webb Space Telescope (JWST) is revolutionizing the search for life beyond our solar system, offering humanity its most detailed look yet at distant, potentially habitable worlds. With its extraordinary infrared capabilities, Webb is not only detecting atmospheres on small rocky exoplanets but also probing their chemical makeup in search of biosignatures—clues that could hint at the presence of life. However, scientists caution that context is everything. Atmospheric data alone is not enough to confirm life; understanding a planet’s surface, interior, and broader environment is essential. Even detecting a potential biosignature, such as a gas possibly produced by biological processes, doesn’t equate to discovery. Multiple, independent lines of evidence would be needed to confirm such a find. “F...

Webb Telescope Reveals Tangled Rings and Dusty Chaos in Dying Star System NGC 1514.

NASA’s James Webb Space Telescope has captured the most detailed image yet of planetary nebula NGC 1514, revealing clumpy dust rings and clear holes in its vibrant pink core using mid-infrared light. A dying star’s final performance has been brought into sharp focus by NASA’s James Webb Space Telescope, revealing a cosmic display of tangled rings, drifting dust, and mysterious holes in the planetary nebula NGC 1514. This mesmerizing structure lies about 1,500 light-years away in the constellation Taurus and has been evolving for at least 4,000 years. At the heart of the nebula are two tightly bound stars, orbiting each other every nine years, their light diffracted in Webb’s images like a celestial jewel. While the stars appear as one in mid-infrared light, they are central to the nebula’s complex architecture. One of these stars, once several times the mass of our Sun, ejected its outer layers in a slow, dense stellar wind as it aged. The other star’s close approach may have twi...

Astronomers have discovered a 'Death Star' black hole in action.

A team of astronomers has studied 16 supermassive black holes that are firing powerful beams into space, tracking where these beams, or jets, are pointing now and where they were aimed in the past, as reported in our latest press release. Using NASA’s Chandra X-ray Observatory and the U.S. National Science Foundation (NSF) National Radio Astronomical Observatory’s (NRAO) Very Large Baseline Array (VLBA), they found that some of the beams have changed directions by large amounts. These two Chandra images show hot gas in the middle of the galaxy cluster Abell 478 (left) and the galaxy group NGC 5044 (right). The center of each image contains one of the sixteen black holes firing beams outwards. Each black hole is located in the center of a galaxy embedded in the hot gas. In the images below, labels and the radio images appear. Ellipses show a pair of cavities in the hot gas for Abell 478 (left), while ellipses indicate two pairs of cavities for NGC 5044 (right). These cavities were carve...
