Day 16 - Night Sky Observatory

Today marks a milestone in the Night Sky Observatory build - the completed observatory (in manual mode)!

In the next few days I will be starting the move of telescopes and equipment into the building. A desk and computer system has already been placed in one of the bays. 

The Celestron EdgeHD11 is being cleaned and prepped for new cable runs. The clear coat on the scope has weathered badly and is flaking off, so I decided to remove it completely and apply thermal covering to the OTA tube. That will be accomplished tomorrow. 

I have yet to contract an electrician to run the AC and network cables so I will be using a long extension cord for power and either WiFi or another long CAT5 cable run for connectivity as a temporary solution to get things up and running. 

I'm still not sure exactly how the cables will be routed so I'll be experimenting with that as well in the next couple of months. My desire is to get basic functionality by end of this month (or sooner).

Saturn has a Decagon Cloud

Astronomers have confirmed a remarkable new feature at Saturn’s south pole: a giant 10-sided atmospheric wave, known as a decagon. The structure was first hinted at in Hubble Space Telescope images from 2023 and became increasingly clear in observations through 2025. Researchers announced the discovery in 2026 after confirming that the pattern forms a distinct, large-scale geometric shape encircling the pole.

The discovery is especially intriguing because Saturn is already famous for the long-lived hexagon at its north pole. While the new southern decagon appears similar, scientists believe it may represent a different atmospheric phenomenon. The decagon is embedded within a powerful jet stream and extends through multiple layers of Saturn’s atmosphere, suggesting it is more than just a cloud pattern. Researchers are now monitoring it to determine whether it will become a stable feature like the northern hexagon or continue to evolve, offering a rare opportunity to observe the formation of a major planetary weather system in real time.

Night Sky Observatory Build - Day 14 and 15

Day 14, August 29th, the dome assembly was completed - stainless steel track plates were screwed to the bottom flange of the dome to provide support and a running surface for the wheels on top of the building. I needed to climb in there on my back and screw-in the plates - good thing it was cool that day.

Today (day 15) marks a milestone in the build - the dome was lifted unto the walls! Six guys from my church, including my pastor, Quint Merson of Crosslife Bible Church, who scheduled the team to come over early this morning, lifted the dome safely onto the building walls. Just a few more tasks to complete on the inside of the dome and she will be ready for manual mode.

Lifting the dome - most of the guys are behind the building!

Nancy Grace Roman - the New Kid on the Block

NASA’s Nancy Grace Roman Space Telescope is expected to transform astronomy by combining Hubble-like image quality with an enormously wider field of view. Roman can survey the sky more than 1,000 times faster than Hubble at similar resolution, generating an unprecedented amount of data and allowing scientists to study vast regions of the universe rather than isolated targets. The mission is designed to investigate some of astronomy’s biggest questions, including the nature of dark matter, dark energy, galaxy evolution, and the distribution of planets throughout the Milky Way.

One of Roman’s major goals is to discover and characterize exoplanets using a technique called gravitational microlensing. By continuously monitoring hundreds of millions of stars near the center of the Milky Way, the telescope is expected to detect a huge variety of planets, including worlds that are difficult or impossible to find with other methods. Scientists expect Roman to greatly expand the known census of planets and provide new insights into how planetary systems form and evolve across different parts of our galaxy.

Roman will also tackle some of the biggest mysteries in cosmology. Through large-scale surveys of distant galaxies and thousands of Type Ia supernovae, it will create detailed maps of the universe across billions of years of cosmic history. These observations will help researchers measure how the universe has expanded over time and test current theories about dark energy and the standard cosmological model. The telescope’s surveys are expected to reveal billions of galaxies and capture many transient events such as supernovae, gamma-ray bursts, and other rare phenomena.

Another key feature is Roman’s advanced coronagraph, a technology demonstration that blocks starlight to directly observe faint objects nearby, such as exoplanets and debris disks. The instrument is intended to pave the way for future missions capable of imaging Earth-like worlds. The article also highlights Roman’s commitment to open science: its data will become publicly available within hours of processing, and cloud-based tools will make the enormous dataset accessible to researchers around the world. The mission’s scientists expect Roman not only to answer existing questions but also to uncover entirely unexpected discoveries.

NASA’s Nancy Grace Roman Telescope launches to space

NASA’s Nancy Grace Roman Space Telescope launched on August 30, 2026, aboard a SpaceX Falcon Heavy rocket from Kennedy Space Center after more than a decade of development. The observatory is headed to the Sun-Earth L2 Lagrange point, about a million miles beyond Earth, where it will have a stable view of the universe while remaining in constant contact with mission controllers. NASA officials reported that the launch and initial spacecraft systems appeared to be operating normally, with instrument calibration and commissioning scheduled over the coming weeks.

From SpaceX Live Feed - Sunday, August 30, 2026

Roman’s mission is expected to complement the Hubble and James Webb space telescopes by conducting enormous sky surveys and investigating some of astronomy’s biggest mysteries. Its primary goals include studying dark matter and dark energy, creating a vast census of exoplanets, and mapping stars and galaxies on an unprecedented scale. The telescope also carries a powerful coronagraph designed to directly observe planets around other stars by blocking starlight, potentially allowing scientists to study the atmospheres of distant worlds. NASA officials said Roman could dramatically increase the number of known exoplanets and help answer fundamental questions about whether habitable Earth-like planets exist elsewhere in the universe. The mission’s initial science phase is expected to last five years, with the first images anticipated after commissioning is completed.

Nancy Grace Roman's Special Coronagraph

Although NASA's Nancy Grace Roman Space Telescope is primarily known for its powerful wide-field survey capabilities, its most important long-term contribution may be a smaller, experimental instrument hidden inside it: an advanced coronagraph. The coronagraph is designed to block the overwhelming light of a star so astronomers can directly observe much fainter planets orbiting nearby. Roman's version is far more sophisticated than the coronagraphs flown on Hubble or James Webb because it incorporates adaptive optics and deformable mirrors that can actively reshape themselves to counter tiny optical distortions.

This technology is a crucial steppingstone toward a future telescope capable of photographing Earth-like planets around Sun-like stars. Roman's coronagraph faces an extraordinary challenge, likened to spotting a firefly beside a floodlight from across the country. By testing active wavefront control and ultra-precise light suppression in space for the first time, NASA hopes to learn what is needed for future missions such as the proposed Habitable Worlds Observatory. Even if the coronagraph itself produces only a limited number of exoplanet images, its real value is demonstrating a technology that could eventually help scientists search for worlds that may resemble Earth.

Days 11-13 - Night Sky Observatory Build

Over the past few weeks, I've been able to spend a few hours (over three days) to make great progress on completing the 'Night Sky Observatory'. Wheels have been added to the top of the building; the dome has been completed with the exception of the steel plates that are screwed to the bottom of the dome serving as a track for the dome wheels to ride along. The plates require at least two people to get them attached. My friend Tina will be coming over later today to help with the final stage of the dome assembly. Then it's just a matter of getting about 4-6 strong guys to lift the dome on top of the building.

Almost Total: Watch the Moon Slip into Earth's Shadow Tonight

Tonight's lunar eclipse is a deep partial lunar eclipse, meaning it falls just short of being total. At the moment of greatest eclipse, about 96% of the Moon will be immersed in Earth's dark umbral shadow, making it appear almost completely eclipsed. The event is visible across Africa, Europe, most of the Americas, and the eastern Pacific region, provided the Moon is above the horizon and the sky is dark at the time. The entire eclipse lasts about 5 hours and 39 minutes, with the partial phase lasting more than 3 hours.

Robert Hall in South Mississippi took this image of the lunar eclipse on November 19, 2021.

Observers won't need any special equipment; the eclipse is safe to view with the naked eye, although binoculars or a telescope can enhance the experience. As Earth's shadow moves across the Moon, it will first appear as a dark "bite" taken from its edge. Near maximum eclipse, the shadowed portion may take on a reddish hue, caused by sunlight filtering through Earth's atmosphere and bending onto the Moon. Because a small sliver of the Moon remains outside the shadow, viewers should also see a bright white patch along one edge, creating a dramatic contrast during the peak of the event.

While clouds are expected over Maryland and the surrounding area, lucky observers may still catch a quick view of the eclipse through occasional clear patches. Read the full article at: EarthSky

Pluto's Atmosphere is Thinning

Pluto’s atmosphere appears to be shrinking as the dwarf planet travels farther from the Sun. Scientists studying observations from 2017 to 2023 found that its atmospheric pressure dropped by about 16% between mid-2021 and July 2023. They measured this by observing Pluto as it passed in front of distant stars, a technique that lets researchers study the properties of its thin atmosphere.

NASA calls this image “Pluto’s Blue Sky.”
It’s a backlit view of Pluto, acquired by the New Horizons spacecraft as it sped away from
the dwarf planet after its 2015 flyby.

Researchers have long predicted that Pluto’s nitrogen-rich atmosphere would gradually freeze onto its surface as the planet moved into colder regions of the solar system. The new findings may be the first clear evidence that this process is underway. While Pluto’s atmosphere remained relatively stable after the New Horizons flyby in 2015, the recent decline suggests that it could continue thinning and eventually undergo the atmospheric collapse scientists have expected for decades.

Falcon 9's Crater on the Moon

A SpaceX Falcon upper stage crashed into the Moon on August 5 when its orbit intersected with the Moon’s path. The stage had previously launched two lunar landers—Firefly Aerospace’s Blue Ghost and ispace’s Resilience—toward the Moon. Weighing about 4,000 kilograms, it impacted the lunar surface at nearly 9,000 kilometers per hour. The booster struck the Moon’s near side, close to Einstein crater.

A few days later, between August 11 and 12, NASA’s Lunar Reconnaissance Orbiter (LRO) captured images of the newly formed crater from an altitude of about 96 kilometers. The LRO operates in a polar orbit around the Moon, imaging the surface directly beneath it as the Moon rotates. This imaging pattern explains the six-day gap between the impact and the acquisition of the crater photographs.
