The Hubble Space Telescope celebrated its 33rd year in orbit by premiering a stunning new Hubble image of a nearby star-forming region named NGC 1333. Even after all these years, Hubble continues to uncover the mysteries of the universe. These are a few science achievements from Hubble’s latest year in orbit.

In October 2023, NASA is launching the Heliophysics Big Year – a global celebration of solar science and the Sun’s influence on Earth, our solar system, and beyond. Modeled after the “Big Year” concept from citizen scientists in the bird-watching community, the Heliophysics Big Year challenges everyone to get involved with fun Sun-related activities.

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.

Using NASA’s Neil Gehrels Swift Observatory, which launched in 2004, scientists have discovered a black hole in a distant galaxy repeatedly nibbling on a Sun-like star. The object heralds a new era of Swift science made possible by a novel method for analyzing data from the satellite’s X-ray Telescope (XRT). When a star strays too close to a monster black hole, gravitational forces create intense tides that break the star apart into a stream of gas. The leading edge swings around the black hole, and the trailing edge escapes the system. These destructive episodes are called tidal disruption events. Astronomers see them as flares of multiwavelength light created when the debris collides with a disk of material already orbiting the black hole. Recently, astronomers have been investigating variations on this phenomena, which they call partial or repeating tidal disruptions. During these events, every time an orbiting star passes close to a black hole, the star bulges outward and sheds material, but survives. The process repeats until the star looses too much gas and finally breaks apart. The characteristics of the individual star and black hole system determine what kind of emission scientists observe, creating a wide array of behaviors to categorize. On June 22, 2022, XRT captured Swift J0230 for the first time. It lit up in a galaxy around 500 million light-years away in the northern constellation Triangulum. Swift’s XRT has observed nine additional outbursts from the same location roughly every few weeks. Scientists propose that Swift J0230 is a repeating tidal disruption of a Sun-like star orbiting a black hole with over 200,000 times the Sun’s mass. They estimate the star loses around three Earth masses of material on each pass. This system provides a bridge between other types of suspected repeating disruptions and allowed scientists to model how interactions between different star types and black hole sizes affect what we observe. Swift J0230’s discovery was possible thanks to a new, automated search of XRT observations called the Swift X-ray Transient Detector. After the instrument observes a portion of the sky, the data is transmitted to the ground, and the program compares it to previous XRT snapshots of the same spot. If that portion of the X-ray sky has changed, scientists get an alert. In the case of Swift J0230, astronomers were able to rapidly coordinate additional observations of the region.

The 2023 Antarctic ozone hole reached its maximum size at 10 million square miles, or 26 million square kilometers, on Sept. 21, which ranks as the 16th largest since 1979, according to annual satellite and balloon-based measurements made by NASA and NOAA. During the peak of the ozone depletion season from Sept. 7 to Oct. 13, the hole averaged 8.9 million square miles (23.1 million square kilometers), approximately the size of North America.

NASA's Swift satellite has acquired the highest-resolution view of the neighboring spiral galaxy M31. Also known as the Andromeda Galaxy, M31 is the largest and closest such galaxy to our own. It's more than 220,000 light-years across and lies 2.5 million light-years away in the constellation Andromeda. Between May 25 and July 26, 2008, Swift's Ultraviolet/Optical Telescope (UVOT) acquired 330 images of M31 at wavelengths of 192.8, 224.6, and 260 nanometers. The images represent a total exposure time of 24 hours. Some 20,000 ultraviolet sources are visible in the image, including M32, a small galaxy in orbit around M31. Dense clusters of hot, young, blue stars sparkle in the disk beyond the galaxy's smooth, redder central bulge. Star clusters are especially plentiful along a ring about 150,000 light-years across.

Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the sun's atmosphere, the corona. On July 19, 2012, an eruption occurred on the sun that produced all three. A moderately powerful solar flare exploded on the sun's lower right hand limb, sending out light and radiation. Next came a CME, which shot off to the right out into space. And then, the sun treated viewers to one of its dazzling magnetic displays -- a phenomenon known as coronal rain. Over the course of the next day, hot plasma in the corona cooled and condensed along strong magnetic fields in the region. Magnetic fields, themselves, are invisible, but the charged plasma is forced to move along the lines, showing up brightly in the extreme ultraviolet wavelength of 304 Angstroms, which highlights material at a temperature of about 50,000 Kelvin. This plasma acts as a tracer, helping scientists watch the dance of magnetic fields on the sun, outlining the fields as it slowly falls back to the solar surface. The footage in this video was collected by the Solar Dynamics Observatory's AIA instrument. SDO collected one frame every 12 seconds, and the movie plays at 30 frames per second, so each second in this video corresponds to 6 minutes of real time. The video covers 12:30 a.m. EDT to 10:00 p.m. EDT on July 19, 2012.

A number of people who've seen NASA's annual lunar phase and libration videos have asked what the other side of the Moon looks like, the side that can't be seen from the Earth. This video answers that question. The imagery was created using Lunar Reconnaissance Orbiter data.

Our Universe is not silent.. Although space is a vacuum, that does not mean there is no sound in it. Yes, space is a vacuum - so it generally doesn't carry sound waves like air does here on Earth. However, some sounds do exist in outer space, we just can't hear them. Various probes that zoom through the space are capable of capturing radio emissions from astronomical objects. NASA's scientist have designed special instrument known as 'astronomical interferometer' which can record these electromagnetic vibrations, and transfer them into sounds within range of human hearing (20-20,000 Hz). Interesting Facts about our Moon: The Moon's Latin name is Luna. The Moon formed approx. 4.5 billion years ago. Moon is the fifth-largest natural satellite in the Solar System. The moon orbits the Earth at an average speed of 3,700 kilometers an hour. The Moon is in synchronous rotation with Earth - it is always shows Earth the same side. The Moon’s surface is dark. The dark side of the Moon cools to about -169 degrees Celsius. During the lunar day that lasts about a month Moon's surface bakes in the sun at up to 117 degrees Celsius. The Moon is drifting away from the Earth approx. 3.8 cm every year. The Moon has quakes called the Moonquakes. There is water on the Moon. The Soviet Union’s Luna program featured the first successful landing of an unmanned spacecraft on the surface of the Moon in 1966. The USA’s NASA Apollo 11 mission in 1969 was the first manned Moon landing. The first person to set foot on the Moon was Neil Armstrong. A lunar eclipse occurs when the Earth is between the Sun and the Moon. The Moons is actually more of an oval shape. The Moon is international property. Apollo 17 astronaut Harrison Schmitt was allergic to the Moon. Astronauts have brought 842 pounds of moon material back to Earth. The dark spots on the moon are called maria.

When a star wanders too close to a black hole, intense tidal forces rip the star apart. In these events, called “tidal disruptions,” some of the stellar debris is flung outward at high speed while the rest falls toward the black hole. This causes a distinct X-ray flare that can last for a few years. NASA’s Chandra X-ray Observatory, Swift Gamma-ray Burst Explorer, and ESA/NASA’s XMM-Newton collected different pieces of this astronomical puzzle in a tidal disruption event called ASASSN-14li, which was found in an optical search by the All-Sky Automated Survey for Supernovae (ASAS-SN) in November 2014. The event occurred near a supermassive black hole estimated to weigh a few million times the mass of the sun in the center of PGC 043234, a galaxy that lies about 290 million light-years away. Astronomers hope to find more events like ASASSN-14li to test theoretical models about how black holes affect their environments. During the tidal disruption event, filaments containing much of the star's mass fall toward the black hole. Eventually these gaseous filaments merge into a smooth, hot disk glowing brightly in X-rays. As the disk forms, its central region heats up tremendously, which drives a flow of material, called a wind, away from the disk.
