NASA’s Parker Solar Probe Completes 20th Close Approach to the Sun.

Parker Solar Probe’s 20th orbit included a perihelion that brought the spacecraft within 4.51 million miles of the Sun, showcasing the mission's continued success in gathering unprecedented data from the solar environment.

NASA’s Parker Solar Probe achieved its 20th close approach to the Sun on June 30, 2024, coming within about 4.51 million miles (7.26 million kilometers) of the solar surface, matching its own distance record.

The perihelion occurred at 3:47 UTC (11:47 p.m. EDT on June 29), with the probe traveling at a speed of 394,736 miles per hour (635,266 kilometers per hour), also matching its previous speed record. On July 2, the spacecraft communicated with mission operators at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, confirming it was in good health and all systems were functioning normally. This achievement marks the midpoint of the mission’s 20th solar encounter, which started on June 25 and will continue until July 5.

The Parker Solar Probe is scheduled to make another close approach at the same distance and speed on September 30, 2024. Following this, it will begin its final series of approaches, with the first of three closest approaches planned for December 24, 2024. After a final Venus gravity assist-flyby on November 6, the spacecraft will approach within just 3.8 million miles of the Sun's surface, traveling at approximately 430,000 miles per hour.

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...
