The Gemini South telescope has captured a new image of the glowing nebula IC 2220. Nicknamed the Toby Jug Nebula, this object got its name because it looks like an old English jug. But no fun drinking games are happening here.

As of 2019, China began conducting preliminary studies for a crewed lunar mission that would take place by the 2030s. Two years later, the China National Space Agency (CNSA) and Roscosmos announced a partnership to create an International Lunar Research Station (ILRS) around the South Pole-Aitken Basin. The proposed timeline for development came down to three phases: Reconnaissance (2021-25), Construction (2025-35), and Utilization (2035-onward). Earlier this year, China announced that its space agency would send the first crewed mission to the lunar surface by 2030.
On July 12th, during the 9th China (International) Commercial Aerospace Forum in Wuhan, China, Chinese officials offered additional information about its crewed lunar exploration program. This included Deputy chief engineer Zhang Hailian of the China Manned Space Engineering (CMSE) office announcing the preliminary plan for China’s first crewed lunar mission. As Zhang illustrated with a series of animations, the mission will consist of two carrier rockets launching all the necessary elements to the Moon, which will then rendezvous in orbit and land on the surface to conduct science operations.

Nuclear fusion is what separates stars from planets. Stars are massive enough to fuse hydrogen in their cores, while planets are not. But in between these two categories are brown dwarfs, which are massive enough to experience some nuclear fusion, just not hydrogen. The largest of them are hot and star-like. The smallest of them are barely warm enough to bake a pizza.

NASA recently selected a new science payload that will travel to the Moon through a series of robotic missions via the agency’s Artemis program. This instrument suite, known as the Dating an Irregular Mare Patch with a Lunar Explorer (DIMPLE), will have the task of studying the Ina Irregular Mare Patch, also known as Ina, which is a small depression that could provide insights into the Moon’s volcanic history. It was discovered using orbital images from the Apollo 15 crew, and despite several past studies, its origin remains unclear.

The search for life on Mars has been a long a confusing one. Inconclusive experiments abound, but one thing is certain – there is definitely organic material on the Red Planet. Now, a new study in Nature has confirmed that finding and showed just how complex that organic material actually is.

Satellites often offer new perspectives when they launch. Sometimes because of the location they are placed in – sometimes because of their instrumentation. A new satellite by a consortium of European companies and agencies now provides a new perspective on one of the most powerful and fleeting natural phenomena – lightning.

On July 14, 2023, at 2:35 pm Indian Standard Time (5:05 am EST), the Indian Space Resource Organisation (ISRO) successfully launched their Chandrayaan-3 spacecraft from the Satish Dhawan Space Center, which is the primary spaceport of the ISRO. The goal of the mission is to put India’s first lander (Vikram) and rover (Pragyan) on the lunar surface and is scheduled to touch down on the Moon on August 23, 2023. This mission comes after the ISRO’s Chandrayaan-2 Vikram lander crashed on the Moon on September 6, 2019, due to a last-minute guidance software glitch. While the ISRO indicated everything was going according to plan, they unexpectedly lost contact with the Vikram lander approximately 2.1 kilometers (1.3 miles) above the lunar surface.

It’s easy to think of Earth as a water world, with its vast oceans and beautiful lakes, but compared to many worlds, Earth is particularly wet. Even the icy moons of Jupiter and Saturn have far more liquid water than Earth. Earth is unusual not because it has liquid water, but because it has liquid water in the warm habitable zone of the Sun. And as a new study in Nature Communications shows, Earth could be even more unusual than we thought.

A recent study presented at the National Astronomy Meeting 2023 (NAM2023) examines a newly discovered planetary formation theory that challenges previous notions on how planets are formed in the disks of gas and dust surrounding young stars, also known as protoplanetary disks. Along with being presented at NAM2023, the study has also been submitted for peer-review to the journal Monthly Notices of the Royal Astronomical Society and holds the potential to help scientists better understand not only how planets form, but how life could form on them, as well.

When the James Webb Space Telescope started collecting data, it gave us an unprecedented view of the distant cosmos. Faint, redshifted galaxies seen by Hubble as mere smudges of light were revealed as objects of structure and form. And astronomers were faced with a bit of a problem. Those earliest galaxies seemed too developed and too large to have formed within the accepted timeline of the universe. This triggered a flurry of articles claiming boldly that JWST had disproven the big bang. Now a new article in the Monthly Notices of the Royal Astronomical Society argues that the problem isn’t that galaxies are too developed, but rather that the universe is twice as old as we’ve thought. A whopping 26.7 billion years old to be exact. It’s a bold claim, but does the data really support it?
