Planet Uranus | James Webb Space Telescope

Planet Uranus | James Webb Space Telescope

This image of Uranus from the near-infrared camera (NIRCam) on the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope shows the planet and its rings in new clarity. The planet’s seasonal north polar cap gleams in a bright white, and Webb’s exquisite sensitivity resolves Uranus’ dim inner and outer rings, including the Zeta ring—the extremely faint and diffuse ring closest to the planet.

This Webb image also shows 14 of the planet’s 27 moons: Oberon, Titania, Umbriel, Juliet, Perdita, Rosalind, Puck, Belinda, Desdemona, Cressida, Ariel, Miranda, Bianca, and Portia.

One day on Uranus is about 17 hours, so the planet’s rotation is relatively quick. This makes it supremely difficult for observatories with a sharp eye like Webb to capture one simple image of the entire planet—storms and other atmospheric features, and the planet’s moons, move visibly within minutes. This image combines several longer and shorter exposures of this dynamic system to correct for those slight changes throughout the observing time.

Webb’s extreme sensitivity also picks up a smattering of background galaxies—most appear as orange smudges, and there are two larger, fuzzy white galaxies to the right of the planet in this field of view.

Spiral Galaxy MCG-01-24-014 in Hydra | Hubble

Spiral Galaxy MCG-01-24-014 in Hydra | Hubble

This whirling image features a bright spiral galaxy known as MCG-01-24-014. It is located about 275 million light-years from Earth. In addition to being a well-defined spiral galaxy, MCG-01-24-014 has an extremely energetic core, known as an active galactic nucleus (AGN), so it is referred to as an active galaxy. Even more specifically, it is categorized as a Type-2 Seyfert galaxy. Seyfert galaxies host one of the most common subclasses of AGN, alongside quasars. While the precise categorization of AGNs is nuanced, Seyfert galaxies tend to be relatively nearby ones where the host galaxy remains plainly detectable alongside its central AGN, while quasars are invariably very distant AGNs whose incredible luminosities outshine their host galaxies.

Image Description: A spiral galaxy. It appears to be almost circular and seen face-on, with two prominent spiral arms winding out from a glowing core. It is centered in the frame as if a portrait. Most of the background is black, with only tiny, distant galaxies, but there are two large bright stars in the foreground, one blue and one red, directly above the galaxy.

There are further subclasses of both Seyfert galaxies and quasars. In the case of Seyfert galaxies, the predominant subcategories are Type-1 and Type-2. These are differentiated from one another by their spectra—the pattern that results when light is split into its constituent wavelengths—where the spectral lines that Type-2 Seyfert galaxies emit are particularly associated with specific so-called ‘forbidden’ emission. To understand why emitted light from a galaxy could be considered forbidden, it helps to understand why spectra exist in the first place. Spectra look the way they do because certain atoms and molecules will absorb and emit light very reliably at very specific wavelengths. The reason for this is quantum physics: electrons (the tiny particles that orbit the nuclei of atoms and molecules) can only exist at very specific energies, and therefore electrons can only lose or gain very specific amounts of energy. These very specific amounts of energy correspond to certain light wavelengths being absorbed or emitted.

Forbidden emission lines, therefore, are spectral emission lines that should not exist according to certain rules of quantum physics. Nevertheless, quantum physics is complex, and the rules adopted to predict it use assumptions that suit laboratory conditions here on Earth. Under those rules, this emission is ‘forbidden’—so improbable that it’s disregarded. However, in space, in the midst of an incredibly energetic galactic core, those assumptions do not hold anymore, and the ‘forbidden’ light gets a chance to shine out towards us.

Fireball over Pennsylvania | Geminid Meteor Shower 2023

Fireball over Pennsylvania | Geminid Meteor Shower 2023

Astrophotographer Tom Wildoner: "Snagged this beauty early in the morning on December 16, 2023 while testing a ZWO ASI071MC and Samyang Lens. You can still capture some Geminid meteors before and after the peak dates."

Every December we have a chance to see one of our favorite meteor showers—the Geminids. All meteors appear to come from the same place in the sky called the radiant. The Geminids appear to radiate from a point in the constellation Gemini, hence the name “Geminids.”

The Geminids are typically rich in green-colored fireballs like this one!

The Geminids are caused by debris from a celestial object known as 3200 Phaethon, whose origin is the subject of debate. A number of astronomers consider it to be an extinct comet, based on observations showing a small amount of material leaving Phaethon’s surface. Others argue that it has to be an asteroid because of its orbit and its similarity to the main-belt asteroid Pallas.

Whatever the nature of Phaethon, observations show that the Geminids are denser than meteors belonging to other showers, enabling them to get as low as 29 miles above Earth’s surface before burning up. Meteors belonging to other showers, like the Perseids, burn up much higher.

The Geminids can be seen by most of the world. Yet, it is best viewed by observers in the Northern Hemisphere. As you enter the Southern Hemisphere and move towards the South Pole, the altitude of the Geminid radiant—the celestial point in the sky where the Geminid meteors appear to originate—gets lower and lower above the horizon. Thus, observers in these locations see fewer Geminids than their northern counterparts.

Besides the weather, the phase of the Moon is a major factor in determining whether a meteor shower will have good rates during any given year.

Meteors can be colorful. While the human eye usually cannot discern many colors, cameras often can. Colors in meteors usually originate from ionized chemical elements released as the meteor disintegrates. Blue-green colors typically originate from magnesium, calcium radiates violet, and nickel glows green. Red, however, typically originates from energized nitrogen and oxygen in the Earth's atmosphere. This bright meteoric fireball was gone in a flash—less than a second—but it left a wind-blown ionization trail that remained visible.

Space Barber Shop: Chinese Astronaut Gets Haircut | China Space Station

Space Barber Shop: Chinese Astronaut Gets Haircut | China Space Station

On Friday, Dec. 15, 2023, a video showing the Shenzhou-17 crew aboard China's space station getting haircuts and washing their hair was released by the China Manned Space Agency (CMSA). It soon went viral online and drew numerous likes from viewers. A temporary "barber shop" in China's Tiangong Space Station opened as Shenzhou-17 crew members scrubbed up their appearances to give each other haircuts. Shenzhou-17 astronaut Tang Shengjie can be seen giving fellow astronaut Jiang Xinlin a haircut. Shenzhou-17 astronaut Tang Hongbo (crew commander) can also be seen washing and drying his hair.

Tang Shengjie cut the hair of his colleague Jiang Xinlin using a smart device. Then, a vacuum cleaner-like device sucked up the discarded hair strands to avoid any potential safety risk to the space station's hardware.

The video also showed the mission commander Tang Hongbo using special "shower caps" to wash his hair. He put on the first shower cap with shampoo in it and rubbed his hair. Then, he put on the second shower cap containing water to clean his hair, before drying it with a towel.

The three members of the Shenzhou-17 crew have stayed in orbit for nearly 50 days. They have successfully completed assigned tasks, including moving equipment out of the space station for space experiments, managing equipment and facilities, and maintaining experiment facilities for long-term scientific research.

The three Shenzhou-17 astronauts are expected to spend about six months on China's Tiangong Space Station. The Shenzhou-17 crew launched to the station on October 26, 2023. Shenzhou-17 is the sixth spaceflight to the station.

The Sun Emits X2.8 Class Solar Flare | NASA's Solar Dynamics Observatory

The Sun Emits X2.8 Class Solar Flare | NASA's Solar Dynamics Observatory

The Sun emitted a strong X2.8 class solar flare (upper right side) on December 14, 2023, peaking at 12:02 p.m. EST. Solar flares are sudden explosions of energy in the Sun’s atmosphere that can release a large amount of radiation into space. 

NASA’s Solar Dynamics Observatory watches the Sun constantly and captured images of the event.

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

This flare is classified as an X2.8 flare. X-class denotes the most intense flares, while the number provides more information about its strength.
