The magnificent central bar of NGC 2217 (also known as AM 0619-271) shines bright in the constellation of Canis Major (The Greater Dog), in this image taken by the NASA/ESA Hubble Space Telescope. Roughly 65 million light-years from Earth, this barred spiral galaxy is a similar size to our Milky Way at 100,000 light-years across.

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 🔗

Alcyone (25 Eta Tau) in Tau [HIP 17702]
Distance: 368 light-years, Magnitude: 2.85
Alcyone is the brightest star in the Pleiades cluster M45, a binary star orbited by 3 companions. The primary, Alcyone, is 6 times more massive, 8.2 times larger and 2,400 times more luminous than the Sun. Its fast rotation at 215 km/s suggests that the star is a flattened elipsoid.

Distance: 20 light-years, Magnitude: 5.3
Gliese 783 (279 G. Sagittarii) is a binary star system which is approaching the sun at a velocity of about 129 km/s. At this rate, it will be 6.7 light years away in 41,100 years, and ten times brighter than now. The A-B pair's masses are 65%/24% solar and measure 66%/28% the radius of the sun. The two stars are separated by a semi-major axis of 56.3 AUs.

M21 (Open Cluster) in Sagittarius
Magnitude: 5.9
At a distance of 4,250 light years from Earth, this group of 57 various magnitude stars all started life together about 4.6 million years ago as part of the Sagittarius OB1 stellar association. It is located in the galactic disk near the Sagittarius star forming region. The cluster lies near to the nebula NGC 6514 (the Trifid nebula).

Located south of Gemini, its only mark is the 1st-magnitude star Procyon one of the Winter Triangle stars. Since the constellation contains just one more 3rd-magnitude star, Gomeisa, it is impossible to fancy a "little dog". On the flag of Brazil Procyon represents the state of Amazonas.
Star Chart153P/Ikeya-Zhang
Discovered in 2002, 153P/Ikeya-Zhang is a long-periodic comet with the longest known period (366.5 years) for returning comets. On March 18, 2002, the comet last passed perihelion and became the brightest comet since 1997 shining at 3.5 magnitudes. The comets aphelion distance is at over 100 AU away through the Kuiper Belt reaching into the innermost section of the Oort Cloud.
Itokawa (Asteroid)
Semi-major: 1.32276 AU, Size: 0.535 km
Discovered in 1998 and, in 2003, named after a Japanese rocket scientist, the 535 meters small asteroid 25143 Itokawa has been visited by Japan's Hayabusa probe designed to collect soil samples. Hayabusa landed on Nov 20, 2005 for thirty minutes. The sample capsule was returned to Earth on 13 June 2010.
Despina (moon of Neptune)
Despina, discovered in 1989 in Voyager 2 images, is the third closest of Neptune's inner moons with an irregular shape of 180 x148 x128 km. It's orbit is below Neptune's synchronous orbit radius, in that it is slowly spiraling down and will eventually impact or break up in to a ring.
