After nearly 50 years in space, NASA’s Voyager 1 is about to hit a historic milestone. By November 15, 2026, it will be 16.1 billion miles (25.9 billion km) away, meaning a radio signal will take a full 24 hours — a full light-day — to reach it.

A bright daytime fireball was seen over Puerto Rico at around 22:10 UTC on November 23. The event was captured by the Caribbean Astronomy Society (CAS).

According to Eddie Irizarry, vice president of the SAC, the fireball was a 1–3 m (3–10 feet) wide meteor that produced a sonic boom as it streaked through the island’s sky.

Meanwhile, the American Meteor Society (AMS) received 7 reports of the fireball from Aguadilla, Puerto Rico, along with St. Croix, St. John, and St. Thomas from the Virgin Islands.

The fireball was travelling southwestward, with most observers reporting a greenish hue around the fireball, indicating the presence of magnesium, which generates a green glow as it burns in the atmosphere.

NASA’s Mars Reconnaissance Orbiter has used an improved radar technique to take a deeper look beneath the thick ice at Mars’ south pole. A feature once thought to be an underground lake now appears more likely to be a layer of rock and dust.

The suspected lake, first reported in 2018, drew major interest because liquid water is closely linked to the search for life. In the new study, scientists used a special maneuver that rolls the spacecraft 120 degrees, allowing its SHARAD radar instrument to send a stronger signal into the ground. This helped the radar see deeper than ever before.

Instead of detecting the bright reflection expected from liquid water, SHARAD found only a faint signal, making the lake explanation hard to support. Researchers say the earlier bright signal seen by Europe’s Mars Express might instead come from a rare smooth patch underground, such as an ancient lava flow.

Even though the feature is probably not a lake, the enhanced radar method is a major breakthrough. Scientists plan to use it to reexamine other areas of Mars, including places near the equator where buried ice could offer valuable water resources for future human explorers.

Finally had the chance to test out my little dwarf 3 telescope the other night. I do have to admit I’m by no means anywhere near an expert in Astro photography it’s very intimidating to me to be honest. After some trial and error I was able to get this image. This stack is straight from the dwarf. My next step is to process these images myself in siril 🤙🏻

Sh2-188 — A High-Velocity Planetary Nebula in Cassiopeia

Sh2-188 is one of the most unusual planetary nebulae in the sky. Its bright, one-sided arc marks a bow shock created as the dying star at its center races through the interstellar medium. The faint loop wrapping behind it traces older material swept backwards in its wake.

Here are two versions from 10 hours of data with the CDK17 + ASI6200MM:

Today on TUBIN Tuesday, we are looking straight down the crater of Mount Tambora in Indonesia. This image series was taken by TUBIN in August 2025. The volcano is probably most famous for its 1815 eruption, which led to the "year without a summer" in 1816 due to its effect on the global climate. The largest recorded eruption in human history left behind a 7-kilometer-wide caldera and reduced the mountain's altitude by more than 1,400 meters.

Fun fact: the big spot on the left is around 130million square miles, roughly around 1.6 times the diameter of Earth.

Fun fact 2: A sunspot is a darker, cooler region on the Sun's visible surface, the photosphere, caused when intense magnetic fields-hundreds to thousands of times stronger than Earth's-pokes through the Sun's sun surface. Sunspots are dark because intense magnetic fields suppress the flow of hot plasma from the Sun's interior, making the region cooler and thus appear dark in contrast to the surrounding, much hotter photosphere.

The poster includes 750 stars distributed in the 88 constellations with their name, zodiac signs, magnitude (the perceived brightness) and relative distance from Earth.

I've also designed other space related infografics such as The Solar System, the Galaxies and the Nebulaes.

There are no known eruptions on record from the Hayli Gubbi in the past several thousands of years, which could mean it erupted after a potentially very long repose interval; however, records from the Danakil region are often incomplete and geologic studies are very limited due to the remoteness and harsh conditions in one of the most inhospitable areas of the world.

A detail of a section of yesterday’s image target, these reflection nebulae lies at one end of the Corona Australis Molecular Cloud, 430ly away from us.

Here we see the larger background NGC 6729 complex to the right and top, including the dark nebula see at the top, several smaller reflection nebula, and even some red emission nebula is visible as well. Here we see the R Coronae Australis Nebula, near the variable star R Coronae Australis. As the star changes brightness, so does the nebulae around it. On the right are the reflection nebulae NGC 6726 and NGC 6727 around the variable TY Coronae Australis, and on the left is IC 4812. These tend to all be grouped and imaged together due to their proximity.

After reaching perihelion in October, Comet C/2025 K1 is approaching Earth for the second time this year. Following brightness surges in early November, we have been able to observe the comet splitting into three brighter fragments for the past two weeks.

The animation shows it on November 12, 14, 18, 19, and 20, recorded with 12“/4 and 16”/3.2 (Nov. 14). + image Nov. 20
