Atmospheric Carbon Dioxide Tagged by Source | NASA Earth Observatory

Carbon dioxide (CO2) is the most prevalent greenhouse gas driving global climate change. However, its increase in the atmosphere would be even more rapid without land and ocean carbon sinks. They collectively absorb about half of human emissions every year.  Advanced computer modeling techniques in NASA's Global Modeling and Assimilation Office allow us to disentangle the influences of sources and sinks and to better understand where carbon is coming from and going to.

Pan of Jellyfish Galaxy Ka 364 in Cetus | Hubble

Pan of Jellyfish Galaxy Ka 364 in Cetus | Hubble


A jellyfish galaxy with trailing tentacles of stars hangs in inky blackness in this image from the NASA/European Space Agency Hubble Space Telescope. As Jellyfish galaxies move through intergalactic space they are slowly stripped of gas.  This trails behind the galaxy in tendrils illuminated by clumps of star formation. These blue tendrils are visible drifting below the core of this galaxy, and give it its jellyfish-like appearance. This particular jellyfish galaxy—known as JO201—lies in the constellation Cetus. It is named after a sea monster from ancient Greek mythology. This sea-monster-themed constellation adds to the nautical theme of this image.

The tendrils of jellyfish galaxies extend beyond the bright disc of the galaxy core. This particular observation comes from an investigation into the sizes, masses and ages of the clumps of star formation in the tendrils of jellyfish galaxies. Astronomers hope that this will provide a breakthrough in understanding the connection between ram-pressure stripping—the process that creates the tendrils of jellyfish galaxies—and star formation.

This galactic seascape was captured by Hubble's Wide Field Camera 3 (WFC3), a versatile instrument that captures images at ultraviolet and visible wavelengths.

Image Description: A spiral galaxy lies just off-center. It has large, faint, reddish spiral arms and a bright, reddish core. These lie over two brighter blue spiral arms. These are patchy with blotches of star formation. Long trails of these bright blotches trail down from the lower spiral arm, resembling tendrils. The background is black, lightly scattered with small galaxies and stars, and a larger elliptical galaxy in one corner.

Rich Young Star Cluster Cep OB 3b in Cepheus | WIYN Telescope

Rich Young Star Cluster Cep OB 3b in Cepheus | WIYN Telescope

Cep OB 3b is rich young cluster located in the northern constellation of Cepheus. This image was created by combining individual images observed through four different filters on the 0.9 meter telescope at Kitt Peak: blue, visual (cyan), near infrared (orange) and an emission line of hydrogen (red). The brightest yellow star near the center of the image is a foreground star, lying between us and the young cluster. The other bright stars are the massive young stars of the cluster that are heating the gas and dust in the cloud and blowing out cavities. Surrounding these massive cluster stars are thousands of smaller young stars that may be in the process of forming planetary systems.

The Wisconsin-Indiana-Yale-NOIRLab (WIYN) Observatory is situated atop Kitt Peak National Observatory, a partnership consisting of University of California Irvine, Purdue University, the National Science Foundation’s NOIRLab, and NASA.

The Moon & Earth Noctilucent Clouds | International Space Station

The Moon & Earth Noctilucent Clouds | International Space Station


Astronaut Matthew Dominick: "A sliver of Moon rises out of noctilucent clouds and appears to look towards the horizon awaiting the imminent sunrise."
Noctilucent clouds, or night shining clouds, are the highest clouds in Earth's atmosphere, composed of tiny water ice crystals, and are only visible when the sun is below the planet's horizon illuminating them.

The Sun’s activity will once again ramp up until solar maximum, predicted for 2025. This high solar activity is warming Earth's upper atmosphere and breaking apart water molecules required to form noctilucent ices. However, for reasons researchers do not fully understand, Solar Max does not always extinguish the clouds.

Quasar RX J1131-1231: Distance 6 Billion Light-years | James Webb Space Telescope

Quasar RX J1131-1231: Distance 6 Billion Light-years | James Webb Space Telescope


This new James Webb Space Telescope image features the gravitational lensing of the quasar known as RX J1131-1231, located roughly 6 billion light-years from Earth in the constellation Crater. It is considered one of the best lensed quasars discovered to date, as the foreground galaxy smears the image of the background quasar into a bright arc and creates four images of the object.

Image Description: A small image of a galaxy distorted by gravitational lensing into a dim ring. At the top of the ring are three very bright spots with diffraction spikes coming off them, right next to each other. These are copies of a single quasar in the lensed galaxy, duplicated by the gravitational lens. In the center of the ring, the elliptical galaxy doing the lensing appears as a small blue dot. The background is black and empty.

Gravitational lensing, first predicted by Einstein, offers a rare opportunity to study regions close to the black hole in distant quasars, by acting as a natural telescope and magnifying the light from these sources. All matter in the Universe warps the space around itself, with larger masses producing a more pronounced effect. Around very massive objects, such as galaxies, light that passes close by follows this warped space, appearing to bend away from its original path by a clearly visible amount. One of the consequential effects of gravitational lensing is that it can magnify distant astronomical objects, letting astronomers study objects that would otherwise be too faint or far away.

Measurements of the X-ray emission from quasars can provide an indication of how fast the central black hole is spinning. It can provide researchers important clues about how black holes grow over time. For example, if a black hole grows primarily from collisions and mergers between galaxies, it should accumulate material in a stable disc, and the steady supply of new material from the disc should lead to a rapidly spinning black hole. On the other hand, if the black hole grew through many small accretion episodes, it would accumulate material from random directions. Observations have indicated that the black hole in this particular quasar is spinning at over half the speed of light, which suggests that this black hole has grown via mergers, rather than pulling material in from different directions.

This image was captured with Webb’s MIRI (Mid-Infrared Instrument) as part of an observation program to study dark matter. Dark matter is an invisible form of matter that accounts for most of the Universe's mass. Webb’s observations of quasars are allowing astronomers to probe the nature of dark matter at smaller scales than ever before.

Scientists Watch China's Historic Chang'e-6 Far Side Moon Sample Launch

Scientists Watch China's Historic Chang'e-6 Far Side Moon Sample Launch

China's Chang'e-6 mission returned samples from the Moon's far side south pole region for the first time on June 25, 2024 after landing in China's Inner Mongolia Autonomous Region. It was a significant step in space exploration and in international cooperation. The mission carried scientific payloads from France, Italy, Sweden, and Pakistan, including the French radon gas detector (CNES), the European Space Agency/Swedish ion analyzer, and the Italian laser corner reflector (Agenzia Spaziale Italiana). 

A Long March-5 rocket, carrying the Chang'e-6 spacecraft, blasted off from its launchpad at the Wenchang Space Launch Site on the coast of China's southern island province of Hainan on May 3, 2024. International scientists witnessed this historic event.

Among the observers, Stas Barabash, SSPT Program head at the Swedish Institute of Space Physics, expressed his excitement.

"Definitely, it's probably one of the, I think, the most exciting launches I've ever seen in my life," said Barabash.

Pierre-Yves Meslin, DORN principal investigator at IRAP/CNRS, also expressed confidence in the mission.

Aarti Holla-Maini, director of the United Nations Office for Outer Space Affairs, drew a cultural parallel.

"In India, when you get married and it rains, it's considered a blessing from the heavens. So, hopefully this was also a blessing to Chinese sixth," she said.

Christian Feichtinger, executive director of the International Astronautical Federation, shared his enthusiasm for the mission, emphasizing its significance.

"I'm excited and it's a great mission that brings back samples," he said.

Despite concerns about the weather, James Carpenter, acting head of the European Space Agency Lunar Science Office, expressed his confidence in the mission.

"I'm interested to see whether, despite the weather, we are going to go ahead anyway. I think, I think we are going to go ahead," said Carpenter.

Witnessing the successful launch, Neil Melville-Kenney, NILS technical officer at the European Space Agency, conveyed his excitement and offered congratulations.

"What beautiful weather we have. We can see the rocket go. We can hear the rocket go. We're close enough to feel the rocket go. What a fantastic launch! Congratulations!" he said.

Titan is the only planetary body in our solar system, other than Earth, known to have stable liquid on its surface. However, instead of water raining down from clouds and filling lakes and seas as on Earth, on Titan it is methane and ethane—hydrocarbons that we think of as gases but that behave as liquids in Titan’s frigid climate. 

Scientists say it rains methane and ethane there, filling the lakes and seas. These liquids also carve meandering rivers and channels on Titan's surface. 

Titan is larger than the planet Mercury and is the second largest moon in our solar system. Titan’s subsurface water could be a place to harbor life as we know it, while its surface lakes and seas of liquid hydrocarbons could conceivably harbor life that uses different chemistry than we are used to—that is, life as we do not yet know it. 

Titan's lower atmosphere contains carbon-based aerosols that produce haze. This generally blocks visible light, preventing us from seeing the moon's lakes and seas directly. Fortunately, Cassini's ultraviolet light, infrared, and radar instruments allowed this atmospheric layer to be penetrated.

The Cassini-Huygens mission was a cooperative project of NASA, European Space Agency (ESA) and the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the mission for NASA's Science Mission Directorate, Washington. JPL designed, developed and assembled the Cassini orbiter. The radar instrument was built by JPL and the Italian Space Agency, working with team members from the U.S. and several European countries.

The Trifid Nebula in Sagittarius

The Trifid Nebula in Sagittarius

The beautiful Trifid Nebula is a cosmic study in contrasts. Also known as M20, it lies about 5,000 light-years away toward the nebula rich constellation Sagittarius. A star forming region in the plane of our galaxy, the Trifid does illustrate three different types of astronomical nebulae; red emission nebulae dominated by light from hydrogen atoms, blue reflection nebulae produced by dust reflecting starlight, and dark nebulae where dense dust clouds appear in silhouette. 

However, the red emission region, roughly separated into three parts by obscuring dust lanes, is what lends the Trifid its popular name. Pillars and jets sculpted by newborn stars, above and right of the emission nebula's center, appear in famous Hubble Space Telescope close-up images of the region. The Trifid Nebula is about 40 light-years across. Too faint to be seen by the unaided eye, it almost covers the area of a full Moon on planet Earth's sky.

Shenzhou-18 Astronauts Complete Second Spacewalk | China Space Station

Shenzhou-18 Astronauts Complete Second Spacewalk | China Space Station


The Shenzhou-18 astronauts aboard China's orbiting space station completed their second spacewalk at 22:51 (Beijing Time) on Wednesday, July 4, 2024 according to the China Manned Space Agency (CMSA).

Ye Guangfu, Li Cong, and Li Guangsu worked for about 6.5 hours to accomplish multiple tasks with Li Guangsu remaining inside the space station.

With the assistance of the space station's robotic arm and researchers on Earth, they installed space debris protection devices for the pipelines, as well as cables and key equipment outside the Tiangong space station, and conducted an extravehicular inspection.

At 16:19, Li Cong opened the hatch door of the Wentian space lab module and began his first spacewalk.

With the assistance of the space station's robotic arm, Li came to the operation point. Then Ye Guangfu transferred the relevant equipment and devices out of the space station and exited the capsule at 17:41.

Ye climbed to the operation point by himself, and cooperated with Li to install protection devices for the cables of the Wentian lab module and the pipelines of the Tianhe core module.

In the meantime, Li Guangsu carried out monitoring of the robotic arm and provided necessary support from inside the Tianhe core module.

"The main purpose of the spacewalk this time is to install protection devices for extravehicular equipment, mainly cables and pipelines, so as to improve the space station's ability to operate safely and steadily over the long term," said Liu Ming, an engineer with the China Aerospace Science and Technology Corporation (CASC).

After installing protection devices, Li Cong mounted the robotic arm and conducted an extravehicular inspection of the space station's facilities through his helmet camera.

After completing the predetermined tasks, Ye Guangfu and Li Cong returned safely to the Wentian lab module.

"The Chinese space station is very beautiful. Whenever the robotic arm moves to the highest point, I can't help taking more glances at the space station despite the glaring sunlight. I really feel the greatness of the project from my heart, and I applaud all the space professionals and our motherland. We will make continuous efforts to successfully and efficiently complete the follow-up tasks to the end. Let's meet again inside the cabin," Li Cong said outside the space station.

In their previous spacewalk on May 28, the Shenzhou-18 trio mainly installed protection devices for the extravehicular cables of the Mengtian lab module.

The Shenzhou-18 crew, sent to the space on April 25 this year, have completed one third of their space journey and are scheduled to carry out a large amount of in-orbit scientific experiments and technological tests, the agency said.
