The open cluster Westerlund 1, showcased in this new Webb Picture of the Month, is located roughly 12 000 light-years away in the southern constellation Ara (the Altar) where it resides behind a huge interstellar cloud of gas and dust. It was discovered in 1961 from Australia by Swedish astronomer Bengt Westerlund. Westerlund 1 is an incomparable natural laboratory for the study of extreme stellar physics, helping astronomers to find out how the most massive stars in our Galaxy live and die. The unique draw of Westerlund 1 is its large, dense, and diverse population of massive stars, which has no counterpart in other known Milky Way galaxy clusters in terms of the number of stars and the richness of spectral types and evolutionary phases. All stars identified in this cluster are evolved and very massive, spanning the full range of stellar classifications including Wolf-Rayet stars, OB supergiants, yellow hypergiants …

The space shuttle fleet flew 135 missions and helped construct the International Space Station between the first launch on April 12, 1981 and the final landing on July 21, 2011. There were five orbiters: Columbia, Challenger, Discovery, Atlantis and Endeavour.

Just for info, no danger posed. This year, NEO asteroid 2024 TR4, estimated 14 meters across flew past Earth on October 7 at 01:07 UTC at a distance of approximately 112,000 km at a speed of 15 km/sec. The distance equals to 0.3 lunar distances which is a very close encounter (the image shows asteroid Bennu). Link to source 🔗

High proper motion, single star, Barnard's Star is only about 6 light-years away in Ophiuchus. Using ESO's VLT astronomers have detected a rocky planet orbiting at a distance 20 times closer than Mercury is to the sun resulting in a short 3.15 days orbit and a scorching 125°C surface temperature.

According to NASA, on April 13, 2029, Apophis will pass less than 20,000 miles (32,000 kilometers) from Earth's surface, closer than the distance of geosynchronous satellites. Although previously dubbed the Doomsday Asteroid, about 340 meters wide Apophis does not pose any danger of impact during close approach in 2029 as it will be visible with the unaided eye.

Moon is shrinking and torn by tidal forces from Earth. Evidence for seismic activity has been detected near candidate regions for the Artemis III mission scheduled for a crewed lunar landing. Such quakes can produce ground shaking strong enough for faults to slide or for piling up new thrust faults. The LROC image shows a cluster of lobate scarps (left pointing arrows) near the lunar south pole. A thrust fault scarp cut across an approximately 1-km diameter degraded crater (right pointing arrow). Link to source 🔗

Discovered in 2017, the Superterran planet GJ 9827 d is located some 97 light-years away in Pisces and may have a water-rich atmosphere in spite of being hotter than Venus because it orbits extremely close to it host star alongside two further known inner planets. Astronomers will further investigate with the help of the Hubble and James Webb space telescopes. Link to source 🔗

JAXAs lunar lander SLIM has been photographed by its small rover, the Lunar Excursion Vehicle 2 (LEV-2). The soft landing about 55 meters east of target point was completed at 1.4m/sec surpassing specifications. Though the solar panels were supposed to face upwards after landing, on the photo SLIM is shown with its main engine facing upwards, but JAXA hopes it will gather sunlight and restore power until local sunset on Feb 1st. Analysis so far has also revealed that one of the two main engines was lost due to some abnormality at an altitude of 50 meters just before landing. Both exploration rover robots are in good working condition. SLIM landed on the moon at 15:20 on January 19 UTC. Link to source 🔗

Rana (23 Del Eri) in Eri [HIP 17378]
Distance: 29 light-years, Magnitude: 3.54
Delta (23) Eridani, or Rana, Latin for frog, is just under 30 light-years away in Eridanus. Being 3 times more luminous and measuring 2.327 times the radius of the sun, Rana is a subgiant with 1.33 solar masses which has almost depleted its hydrogen, now consuming helium as it expands. The star rotates slowly at 1 km/s.

Distance: 12 light-years, Magnitude: 9.8
Named after Dutch-American astronomer Willem Jacob Luyten, who measured its proper motion, red-orange hued Luyten's Star is a red dwarf, a third the size and a quarter the mass of the Sun. Luyten's star is a slow rotater but moves across the sky at a rate of 3.74 arc seconds per year. It came as close as 11.8 light-years some 13,000 years ago. Its curent distance to its next neighbor Procyon is 1.2 light-years.

Discovered in 1904, the elongated 8km wide 19P/Borelly is a short-period comet orbiting the sun in 6.8 years. On September 2001, NASA's Deep Space 1 probe visited Borelly during an extended mission and sent back detailed images of the surface.
1994 CC (NEO)
Semi-major: 1.63761 AU, Size: 0.7 km
Radar imaging at NASA's Goldstone Solar System Radar on June 12 and 14, 2009, revealed that near-Earth asteroid 1994 CC is a triple system. Asteroid 1994 CC encountered Earth within 2.52 million kilometers on June 10. Prior to the flyby, very little was known about this celestial body. 1994 CC is only the second triple system known in the near-Earth population. 1994 CC consists of a central object about 700 meters in diameter that has two smaller moons revolving around it. Preliminary analysis suggests that the two small satellites are at least 50 meters in diameter.
Ganymede (moon of Jupiter)
Discovered in 1610 by G. Galileo, Ganymede is the third and largest of Jupiter's 'Galilean Satellites', and the largest known moon in the solar system with 0.413 Earth radii. Ganymede is composed of equal amounts of silicate rock and water ice under which a saltwater ocean is believed to exist about 200 km below. Its surface is composed of old impact craters and regions of grooves and ridges with tidally forced tectonic activity. Ganymede is the only moon known to have a magnetossphere. March 2015: NASA's Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter's largest moon. The subterranean ocean is thought to have more water than all the water on Earth's surface. Hubble was used to watch aurorae glowing above the moon's icy surface. The aurorae are tied to the moon's magnetic field, which descends right down to the core of Ganymede. A saline ocean would influence the dynamics of the magnetic field as it interacts with Jupiter's own immense magnetic field, which engulfs Ganymede.
