Observations With Parker Solar Probe’s 7th Solar Encounter
During Parker Solar Probe’s seventh swing by the Sun, celestial geometry posed a special opportunity. The configuration of this particular orbit placed Parker Solar Probe on the same side of the Sun as Earth — meaning that Earth-bound observatories could observe the Sun and its outpouring of solar wind from the same perspective as Parker’s.
Hubble Solves Mystery of Monster Star's Dimming
Last year, astronomers were puzzled when Betelguese, the bright red supergiant star in the constellation Orion, dramatically faded, but then recovered. The dimming lasted for weeks. Now, astronomers have turned their sights toward a monster star in the adjoining constellation Canis Major, the Great Dog.
New ‘Eyewear’ to Deepen the View of NASA’s Roman Space Telescope
NASA’s Nancy Grace Roman Space Telescope will be able to explore even more cosmic questions, thanks to a new near-infrared filter. The upgrade will allow the observatory to see longer wavelengths of light, opening up exciting new opportunities for discoveries from the edge of our solar system to the farthest reaches of space.
How Were the Trojan Asteroids Discovered and Named?
On Feb. 22, 1906, German astrophotographer Max Wolf helped reshape our understanding of the solar system. He discovered the first of a small body of asteroids trapped in Jupiter's orbit. No spacecraft has ever been to this population of small bodies, called the Trojan asteroids. The Lucy mission, launching this year, will be the first.
NASA’s Swift Helps Tie Neutrino to Star-shredding Black Hole
For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy. Using ground- and space-based facilities, including NASA’s Neil Gehrels Swift Observatory, they traced the neutrino to a black hole tearing apart a star, a rare cataclysmic occurrence called a tidal disruption event.
NASA Missions Make Unprecedented Map of Sun’s Magnetic Field
For the first time, a NASA mission has made multi-height measurements of the solar chromosphere’s magnetic field. The observations extend our measurement capability into a region of the Sun that has so far eluded scientific grasp.
