A beautiful video of a solar eruption, also known as a solar flare, captured here by NASA’s Solar Dynamics Observatory. What a spectacle, everyone.
Watch that prominence rise tens of thousands of kilometers, then curve and fall back onto the solar chromosphere, pulled by the immense gravity of our star.

The galaxies that populate the universe have very different shapes and sizes. One of the most common types among these objects is certainly the spiral galaxy, such as the spectacular NGC 2985, located over 70 million light-years from the solar system in the constellation Ursa Major.
Look at how amazing it is in this image captured by the Hubble Space Telescope.

This illustration shows the location of our solar system. As you can see, it is surrounded by a sphere made up of millions of objects composed of rock and ice, known as the Oort Cloud. This shell of celestial bodies is located at a distance ranging between 20,000 and 100,000 astronomical units (1 AU = average Earth-Sun distance, 150 million kilometers). We could perhaps better understand its scale by saying it extends from 0.3 to 1.5 light-years from Earth.
The Oort Cloud has never been directly observed, as it is too distant and too dark even for modern telescopes, but it is believed to be the nursery from which all long-period comets originate, such as Hale-Bopp, for example. This cloud is thought to be a remnant of the nebula from which the Sun and planets were born five billion years ago. It is believed that other stars also have an Oort Cloud and that the outer edges of the clouds of two nearby stars may sometimes overlap.
In 1932, astronomer Ernst Öpik hypothesized that comets originated in a cloud located at the outer edge of the Solar System. This idea was later revisited and refined by Dutch astronomer Jan Oort to explain what appeared to be a contradiction. If comets are periodically destroyed after several passes through the inner solar system and had formed in the beginning, they would all be gone by now. The fact that they can still be observed implies they have a different origin. By observing and studying the orbits of long-period comets, the astronomer theorized the existence of this cloud, which was aptly named after him. Occasionally, one of these comets is perturbed in its orbit and begins to fall toward the Sun.

NASA Astronomy Picture of the Day (2024-11-02): Saturn at Night
https://apod.nasa.gov/apod/image/2411/LastRingPortrait_Cassini_1080.jpg
Saturn is bright in Earth's night skies. Telescopic views of the outer gas giant planet and its beautiful rings often make it a star at star parties. But this stunning view of Saturn's rings and night side just isn't possible from telescopes in the vicinity of planet Earth. Peering out from the inner Solar System they can only bring Saturn's day side into view. In fact, this image of Saturn's slender sunlit crescent with night's shadow cast across its broad and complex ring system was captured by the Cassini spacecraft. A robot spacecraft from planet Earth, Cassini called Saturn orbit home for 13 years before it was directed to dive into the atmosphere of the gas giant on September 15, 2017. This magnificent mosaic is composed of frames recorded by Cassini's wide-angle camera only two days before its grand final plunge. Saturn's night will not be seen again until another spaceship from Earth calls.

NASA Astronomy Picture of the Day (2024-11-01): Spiral Galaxy NGC 6744
https://apod.nasa.gov/apod/image/2411/NGC6744_V2_8_sm1024.jpg
Big, beautiful spiral galaxy NGC 6744 is nearly 175,000 light-years across, larger than our own Milky Way. It lies some 30 million light-years distant in the southern constellation Pavo but appears as only a faint smudge in the eyepiece of a small telescope. We see the disk of the nearby island universe tilted towards our line of sight in this remarkably deep and detailed galaxy portrait, a telescopic image that spans an area about the angular size of a full moon. In it, the giant galaxy's elongated yellowish core is dominated by the light from old, cool stars. Beyond the core, grand spiral arms are filled with young blue star clusters and speckled with pinkish star forming regions. An extended arm sweeps past smaller satellite galaxy NGC 6744A at the upper left. NGC 6744's galactic companion is reminiscent of the Milky Way's satellite galaxy the Large Magellanic Cloud.

NASA Astronomy Picture of the Day (2024-10-31): Rigel and the Witch Head Nebula
https://apod.nasa.gov/apod/image/2410/Strega_apod_1024r.jpg
By starlight, this eerie visage shines in the dark with a crooked profile evoking its popular name, the Witch Head Nebula. In fact, this entrancing telescopic portrait gives the impression that a witch has fixed her gaze on Orion's bright supergiant star Rigel. More formally known as IC 2118, the Witch Head Nebula spans about 50 light-years and is composed of interstellar dust grains reflecting Rigel's starlight. The color of the Witch Head Nebula is caused not only by Rigel's intense blue light, but because the dust grains scatter blue light more efficiently than red. The same physical process causes Earth's daytime sky to appear blue, although the scatterers in Earth's atmosphere are molecules of nitrogen and oxygen. Rigel and this dusty cosmic crone are about 800 light-years away. You may still see a few witches in your neighborhood tonight though, so have a safe and Happy Halloween!

NASA Astronomy Picture of the Day (2024-10-30): NGC 7635: The Bubble Nebula
https://apod.nasa.gov/apod/image/2410/BubbleRed_Leader_960.jpg
What created this huge space bubble? Blown by the wind from a star, this tantalizing, head-like apparition is cataloged as NGC 7635, but known simply as the Bubble Nebula. The featured striking view utilizes a long exposure to reveal the intricate details of this cosmic bubble and its environment. Although it looks delicate, the 10 light-year diameter bubble offers evidence of violent processes at work. Seen here above and right of the Bubble's center, a bright hot star is embedded in the nebula's reflecting dust. A fierce stellar wind and intense radiation from the star, which likely has a mass 10 to 20 times that of the Sun, has blasted out the structure of glowing gas against denser material in a surrounding molecular cloud. The intriguing Bubble Nebula lies a mere 11,000 light-years away toward the boastful constellation Cassiopeia. Your Sky Surprise: What picture did APOD feature on your birthday? (post 1995)
