Close-up of Star-forming Region NGC 6729 in Corona Australis | ESO
This very detailed enhanced-color image from the European Southern Observatory’s Very Large Telescope (VLT) shows the dramatic effects of very young stars on the dust and gas where they were born in star-forming region NGC 6729. The baby stars are invisible in this picture, being hidden behind dust clouds at the upper left of the picture, but material they are ejecting is crashing into the surroundings at speeds of that can be as high as one million kilometers per hour. This picture was taken by the FORS1 instrument and records the scene in the light of glowing hydrogen and sulphur.
Ariane 6: Europe’s New Rocket | European Space Agency
European Space Agency: "Ariane 6 is the newest rocket in a series that has, for five decades, been launching Europe towards the stars. Building on all the knowledge, expertise and technology developed over the years, Ariane 6 will be versatile, modular, and European."
"Guaranteeing Europe’s access to space for the next years, Ariane 6 in two versions, with either two or four boosters attached depending on the ‘oomph’ the mission requires. Versatile, its upper stage can reignite multiple times during a single flight, placing any spacecraft into any orbit—including constellations—saving a final boost to return and burn up in Earth’s atmosphere. Modular, it will be continuously adapted to the needs of the future space sector."
"Four organizations take care of the Ariane 6 program: The European Space Agency (ESA) at the head, ArianeGroup as the main contractor, CNES who designed and built the launchpad and ArianeSpace who sell the launches."
"Thirteen countries contribute, thousands of Europeans have worked on it, and every one of us will benefit from the Earth observation, science, technologies and services it will make possible."

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.

The leading provider of human spaceflight services and developer of human-rated space infrastructure, Axiom Space operates end-to-end missions to the International Space Station today while developing its successor, Axiom Station—the world’s first commercial space station in low-Earth orbit, which will sustain human growth off the planet and bring untold benefits back home."
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.
"Starship is essential to both SpaceX’s plans to deploy its next-generation Starship system as well as for NASA, which will use a lunar lander version of Starship for landing astronauts on the Moon during the Artemis III mission through the Human Landing System (HLS) program."
Fourth SpaceX Starship Flight on June 6, 2024
SpaceX statement on the results:
On June 6, 2024, Starship successfully lifted off at 7:50 a.m. CT from Starbase in Texas and went on to deliver maximum excitement: The Super Heavy booster lifted off successfully and completed a full-duration ascent burn.
Starship executed another successful hot-stage separation, powering down all but three of Super Heavy’s Raptor engines and successfully igniting the six second stage Raptor engines before separating the vehicles.
Following separation, the Super Heavy booster successfully completed its flip maneuver, boostback burn to send it towards the splashdown zone, and jettison of the hot-stage adapter.
The booster’s flight ended with a landing burn and soft splashdown in the Gulf of Mexico seven minutes and 24 seconds into the flight.
Starship's six second stage Raptor engines successfully powered the vehicle to space and placed it on the planned trajectory for coast.
Starship made a controlled reentry, successfully making it through the phases of peak heating and max aerodynamic pressure and demonstrating the ability to control the vehicle using its flaps while descending through the atmosphere at hypersonic speeds.
Starlink on Starship once again enabled real-time telemetry and live high-definition video throughout every phase of entry, with external cameras providing views all the way to the flight’s conclusion.
Flight 4 ended with Starship igniting its three center Raptor engines and executing the first flip maneuver and landing burn since our suborbital campaign, followed by a soft splashdown of the ship in the Indian Ocean one hour and six minutes after launch.
The fourth flight of Starship made major strides to bring us closer to a rapidly reusable future. Its accomplishments will provide data to drive improvements as we continue rapidly developing Starship into a fully reusable transportation system designed to carry crew and cargo to Earth orbit, the Moon, Mars and beyond.
Congratulations to the entire SpaceX team on an inspired fourth flight test of Starship! And thank you to our customers, Cameron County, spaceflight fans, and the wider community for the continued support and encouragement.
At NASA, we are dedicated to pushing the boundaries of innovation and scientific discovery. Like the spirit of Independence Day, our mission is to strive to achieve new heights and forge a path forward in space exploration.
We wish you a safe and happy 4th of July!
Image Description: Astronaut Harrison Schmitt was the first scientist and geologist to visit the Moon. In this picture, astronaut Schmitt, Apollo 17 lunar module pilot, stands near the deployed United States flag on the lunar surface during extravehicular activity (EVA) of NASA's final lunar landing mission in the Apollo series. The Lunar Module (LM) is at left background and the Lunar Roving Vehicle (LRV) at right background (partially obscured). The photo was made by astronaut Eugene Cernan, commander. While astronauts Cernan and Schmitt descended in the LM "Challenger" to explore the Taurus-Littrow region of the moon, astronaut Ronald Evans, command module pilot, remained with the Command and Service Modules (CSM) "America" in lunar orbit. As he returned to the Lunar Module before Cernan, Schmitt is the next-to-last person to have walked on the Moon's surface. Since the death of Cernan in 2017, Schmitt is the most recent person to have walked on the Moon that is still alive.

Binary Star Eta Carinae—A Source of Very High-energy Cosmic Gamma Radiation
The binary star Eta Carinae may be about to explode. However, no one knows when. It may be next year. It may be a million years from now. Eta Carinae's mass—about 100 times greater than our Sun—makes it an excellent candidate for a full blown supernova. Historical records do show that about 170 years ago Eta Carinae underwent an unusual outburst that made it one of the brightest stars in the southern sky. This binary star in the Homunculus Nebula is located 7,500 light-years away in the constellation Carina. Eta Carinae is the only star system currently thought to emit natural LASER light.
With the gamma-ray telescopes of the High Energy Stereoscopic System (H.E.S.S.), astrophysicists have detected very high energy gamma rays from Eta Carinae. It constitutes a new type of source for such high-energy radiation. The DESY animation by Science Communication Lab takes you on an interstellar roadtrip to this extraordinary system.

Global Atmospheric Methane (CH₄) | NASA Earth Observatory
Methane (CH₄) is a powerful greenhouse gas that traps heat 28 times more effectively than carbon dioxide over a 100-year timescale. Concentrations of methane have increased by more than 150% since industrial activities and intensive agriculture began. After carbon dioxide, methane is responsible for about 20% of climate change in the twentieth century. Methane is produced under conditions where little to no oxygen is available.
About 30% of methane emissions are produced by wetlands, including ponds, lakes and rivers. Another 20% is produced by agriculture, due to a combination of livestock, waste management and rice cultivation. Activities related to oil, gas, and coal extraction release an additional 30%. The remainder of methane emissions come from minor sources such as wildfires, biomass burning, permafrost, termites, dams, and the ocean.
Scientists around the world are working to better understand the budget of methane with the ultimate goals of reducing greenhouse gas emissions and improving prediction of environmental change.
The NASA SVS visualization presented here shows the complex patterns of methane emissions produced around the globe and throughout the year from the different sources described above. The visualization was created using output from the Global Modeling and Assimilation Office (GMAO), GEOS modeling system, developed and maintained by scientists at NASA. Wetland emissions were estimated by the LPJ-wsl model, which simulates the temperature and moisture dependent methane emission processes using a variety of satellite data to determine what parts of the globe are covered by wetlands. Other methane emission sources come from inventories of human activity.
