Something mysterious is going on at the Sun. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches from the Sun’s blazing surface. Temperatures in the corona — the Sun’s outer atmosphere — spike to 3 million degrees Fahrenheit, while just 1,000 miles below, the underlying surface simmers at a balmy 10,000 F. How the Sun manages this feat is a mystery that dates back nearly 150 years, and remains one of the greatest unanswered questions in astrophysics. Scientists call it the coronal heating problem. Watch the video to learn how astronomers first discovered evidence for this mystery during an eclipse in the 1800s, and what scientists today think could explain it. Read more:

NASA's Parker Solar Probe mission has returned unprecedented data from near the Sun, culminating in new discoveries published on Dec. 4, 2019, in the journal Nature. Among the findings are new understandings of how the Sun's constant outflow of material, the solar wind, behaves. Seen near Earth -- where it can interact with our planet's natural magnetic field and cause space weather effects that interfere with technology -- the solar wind appears to be a relatively uniform flow of plasma. But Parker Solar Probe's observations reveal a complicated, active system not seen from Earth. Music Credit: Smooth as Glass by The Freeharmonic Orchestra Read more:

At about 10:28 p.m. EST on Nov. 5, Parker Solar Probe will achieve its first perihelion - its first close approach to the Sun - and will come within 15 million miles of the Sun's surface. During perihelion, the spacecraft will reach a top speed of 213,200 miles per hour relative to the Sun. This speed and distance will mark new records for both closest solar approach and top heliocentric speed by a spacecraft. At perihelion, Parker Solar Probe will fly through material at about 3.6 million degrees Fahrenheit. The spacecraft will be protected from intense solar radiation by its Thermal Protection System, or heat shield. Parker Solar Probe employs a host of autonomous systems to keep the spacecraft safe without guidance from Earth — including automatic retraction of the solar panels to regulate their temperature, attitude control using solar limb sensors that ensures all of the instruments remain in the heat shield's shadow, and a sophisticated guidance and control system that keeps the spacecraft pointed correctly. For several days around the Nov. 5 perihelion, Parker Solar Probe will be completely out of contact with Earth because of interference from the Sun's overwhelming radio emissions. Following perihelion, the mission operations team at the Johns Hopkins Applied Physics Laboratory will await a beacon tone from the spacecraft, which will let them know the status of

Nature likes spirals — from the whirlpool of a hurricane, to pinwheel-shaped protoplanetary disks around newborn stars, to the vast realms of spiral galaxies across our universe. Now astronomers are bemused to find young stars that are spiraling into the center of a massive cluster of stars in the Small Magellanic Cloud, a satellite galaxy of the Milky Way.

A star’s death throes have so violently disrupted its planetary system that the dead star left behind, called a white dwarf, is siphoning off debris from both the system’s inner and outer reaches. This is the first time astronomers have observed a white dwarf star that is consuming both rocky-metallic and icy material, the ingredients of planets. Archival data from NASA’s Hubble Space Telescope and other NASA observatories were essential in diagnosing this case of cosmic cannibalism. The findings help describe the violent nature of evolved planetary systems and can tell astronomers about the makeup of newly forming systems. For more information, visit https://nasa.gov/hubble.

Our Milky Way galaxy is haunted. The vast gulf of space between the stars is plied by the dead, burned-out and crushed remnants of once glorious stars. These black holes cannot be directly seen because their intense gravity swallows light. Like legendary wandering ghosts, their presence can only be deduced by seeing how they affect the environment around them. For more information, visit https://nasa.gov/hubble.

The DART mission deployed a kinetic impactor to smack the small moon Dimorphos of the asteroid Didymos on the evening of Sept. 26. This was an on-orbit demonstration of asteroid deflection, a key test of NASA's kinetic impactor technology, designed to impact an asteroid to adjust its speed and path. This particular asteroid moon is NOT a threat to Earth, but is technology being explored to use for when we DO find a potentially hazardous asteroid. The Hubble Space Telescope captured these extraordinary views of the asteroid moon soon after the successful impact. For more information, visit https://nasa.gov/hubble.

The Hubble Space Telescope has taken over 1.5 million observations over the years. One of them is the breathtaking Crab Nebula. With an apparent magnitude of 8.4 and located 6,500 light-years from Earth in the constellation Taurus, the Crab Nebula can be spotted with a small telescope and is best observed in January. The nebula was discovered by English astronomer John Bevis in 1731, and later observed by Charles Messier who mistook it for Halley’s Comet. Messier’s observation of the nebula inspired him to create a catalog of celestial objects that might be mistaken for comets. In this video, Dr. Padi Boyd takes us on a journey through the Nebula, teaching us some of the interesting science behind this famous Hubble image.

An Einstein Ring can be explained by a phenomenon called gravitational lensing, which causes light shining from a faraway galaxy to be warped by the gravity of an object between its source and the observer. This effect was first theorized by Albert Einstein in 1912, and later worked into his theory of general relativity. In this video, Dr. Brian Welch explains this fascinating phenomenon of nature, and goes over how important Hubble is to exploring the mysteries of the universe.

Until the 20th century, astronomers learned virtually all they knew about sources in the sky from only the tiny fraction of electromagnetic radiation that is visible to the eye. However, as astronomers have discovered how to collect radiation outside this part of the spectrum, they have been able to learn much more about the universe. Many objects reveal different aspects of their composition and behavior at different wavelengths. Other objects are completely invisible at one wavelength, yet are clearly visible at another. In this video, Dr. Padi Boyd explains the exciting future of multiwavelength astronomy and how important Hubble is to exploring the mysteries of the universe. For more information.

A young planet whirling around a petulant red dwarf star is changing in unpredictable ways orbit-by-orbit. It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere – causing it to puff off the planet. But during one orbit observed with the Hubble Space Telescope, the planet looked like it wasn’t losing any material at all, while an orbit observed with Hubble a year and a half later showed clear signs of atmospheric loss.

Recent observations from the Hubble Space Telescope show that Neptune's clouds are almost completely disappearing! Astronomers report that their continual monitoring of Neptune’s weather uncovered a link between its shifting cloud abundance and the 11-year solar cycle, where the Sun’s activity waxes and wanes under the driving force of its entangled magnetic field. At present, the cloud coverage seen on Neptune is extremely low, with the exception of some clouds hovering over the giant planet’s south pole. A team of astronomers discovered that the abundance of clouds normally seen at the icy giant’s mid-latitudes started to fade in 2019

Gravitational waves are invisible ripples in the fabric of space-time. They are caused by some of the most violent and energetic events in the universe. These include colliding black holes, collapsing stellar cores, merging neutron stars or white dwarf stars, the wobble of neutron stars that are not perfect spheres and possibly even the remnants of gravitational radiation created by the birth of the universe. In this video, Dr. Padi Boyd explains gravitational waves and how important Hubble is to exploring the mysteries of the universe. For more information, visit https://nasa.gov/hubble.
