- Lunar Farside Mosaic Reveals Thicker Crust — NASA
| The image is a mosaic from the Lunar Reconnaissance Orbiter’s wide angle camera centered on the lunar farside. It combines over 15,000 images acquired between November 2009 and February 2011. The highest resolution version shows features at a scale of 100 meters per pixel. The rough and battered surface of the farside looks very different from the nearside covered with smooth dark lunar maria. A likely explanation is that the farside crust is thicker, making it harder for molten material from the interior to flow to the surface and form dark, smooth maria. The mosaic covers the entire farside hemisphere without any contribution from Earth-based observations. Credit for the composite goes to NASA, GSFC, Arizona State University, and the Lunar Reconnaissance Orbiter team. Source: science.nasa.gov |
- Private Astronaut Balances Motherhood and Spaceflight — Voice of Emirates
Astronaut Kelly Girardi is preparing for a new experience outside Earth. This trip combines her professional ambition in space exploration with her family responsibilities. Girardi gained experience in the rapidly developing field of commercial spaceflight. Preparing for spaceflight presents participants with numerous challenges including training for weightlessness and learning safety procedures. Her story reflects the challenges many women face when pursuing career ambitions while maintaining family ties. The account also notes the psychological preparation required for isolation during missions. Private sector participation continues to expand opportunities for such flights.

Geneva beat Houston and Barcelona in the vote held in Antalya, Turkey. The decision came during the Assembly General of the International Astronautical Federation. Swissmem and the Swiss Space Office led the winning proposal. The congress brings together representatives from space agencies, companies, and universities worldwide. Barcelona had mobilized national institutions and international bodies including the United Nations and ESA for its bid. Houston had positioned its candidacy around the sixtieth anniversary of Apollo. The event will mark the eightieth edition of the annual gathering.

The James Webb Space Telescope used infrared light to peer through dust in a nebula. It revealed many stars of different ages. This helps study how stars change over time. The observations penetrate regions opaque to visible light. Multiple generations of stars appear in the same field of view.

NASA’s SPHEREx space telescope is shedding light on brown dwarfs. New findings published in The Astrophysical Journal show these objects have chemically rich atmospheres. The atmospheres contain water and methane similar to giant planets in our solar system. The survey captures objects too faint for earlier instruments. Systematic mapping allows comparison across a range of temperatures and ages. Source: phys.org - Karl Schwarzschild Born October 9, 1873 — Astronomy Magazine
Schwarzschild was considered a child prodigy and published a paper on celestial mechanics by age 16. He studied astronomy at the University of Strasbourg. He later received recognition for work on general relativity and black holes. His early publications demonstrated advanced mathematical ability. The University of Strasbourg provided foundational training in observational techniques. Source: astronomy.com - Trump Awards Elon Musk National Medal of Science — Space.com

The image shows galaxies warped and multiplied by gravitational lensing from the cluster MACS J0454.1-0300. The orange galaxies appear bunched on one side but are not actually clustered that way. Light from background galaxies bends around the foreground cluster. The effect creates multiple images of the same distant objects. The cluster acts as a natural telescope magnifying background sources. Source: nasa.gov - Copernicus Sentinel-2 Images Namibia Salt Pan — ESA
The image shows Etosha National Park in northern Namibia acquired on April 5, 2026. It captures the country’s biggest salt pan. The salt pan appears as a bright flat expanse amid surrounding terrain. Sentinel-2 provides multispectral data useful for monitoring arid regions. The acquisition date falls during the dry season when surface features stand out clearly.

NASA released a request for proposals to develop commercial stations that could succeed the ISS as early as 2030. Responses are due December 8. NASA plans to select two or more contractors and make a final decision in April. Phase 1 winners receive at least 100 million dollars. Bidders include Axiom Space, Voyager Space, and Vast Space. The solicitation document spans 360 pages and outlines required capabilities. Future phases will fund development, certification, and at least four crewed missions.

The spacecraft undocked after a six-month stay. It previously delivered over 11,000 pounds of supplies and experiments. The departure carried experimental heat shield capsules for testing. Northrop Grumman’s twenty-fourth cargo resupply mission for NASA included the small capsules. The capsules will re-enter to evaluate next-generation thermal protection materials.

White dwarfs normally cannot exceed roughly 1.4 solar masses. Strong magnetic fields could allow growth beyond the Chandrasekhar limit. The finding comes from analysis of stellar remnants. The upper mass limit applies to non-rotating, non-magnetized white dwarfs. Magnetic support could alter the final evolutionary path of some stars.

Cosmic Spotlight
The SPHEREx telescope’s survey of brown dwarfs opens a new window on objects that sit between stars and planets. These worlds show atmospheric chemistry rich in water and methane, mirroring conditions in our own giant planets. The data come from systematic mapping that captures objects too faint for earlier instruments. Scientists can now compare how these atmospheres evolve across a range of temperatures and ages. One open question is whether similar chemistry appears on free-floating planets that formed the same way. The survey adds dozens of new targets for follow-up spectroscopy.
Cosmic Deep Dive: Why the Moon’s Farside Looks So Different
The Moon is about one quarter the diameter of Earth yet its two faces could hardly be more unlike each other. Picture a dinner plate the size of a city block; the nearside would show dark patches the size of several football fields while the farside would look like a single unbroken expanse of lighter, cratered terrain. That difference comes down to crust thickness. The farside crust runs several kilometers deeper on average, enough to keep molten rock from punching through and forming the smooth dark plains we see from Earth. Spacecraft like the Lunar Reconnaissance Orbiter measure this by counting craters and mapping elevation at one hundred meter resolution. The result is a surface that records four billion years of impacts without the resurfacing events that reset the nearside clock. We still do not know exactly why the crust grew thicker on one side in the first place.
