We're Open Tonight!
We're Open Tonight!
The observatory will be open tonight, Sept. 27, 7:30 - 9:00 pm! We expect mostly clear skies, and to see Saturn, the Moon, the Ring Nebula, globular cluster M13, the Andromeda Galaxy, the Double Cluster, and the binary star systems Albireo and Mizar.
Here's a a nice picture of the Double Cluster in the constellation Perseus (we didn't take this picture, but it's similar to what you'd see through our telescopes - you won't see a lot of those dim background stars, though).

Wow - was also an APOD!
Did a reverse image search on the 2nd one to find the original original source. I found some book covers, but eventually this esahubble.org press release revealed itself as at least an official source of the original image from Nov. 2005! It's NGC 346 (the star cluster) and a gorgeous backdrop of gas in the Small Magellanic Cloud.

This is a baby star imaged in stunning detail
Stars are born violently - there's hot gas striking the other gas and dust around it, making these amazing patterns
This particular baby star will one day be like the Sun 💖

This striking image captures the interacting galaxy pair known as Arp-Madore 2339-661, so named because they belong to the Arp-Madore catalogue of peculiar galaxies. However, this particular peculiarity might be even odder than first meets the eye, as there are in fact three galaxies interacting here, not just two.
The two clearly defined galaxies are NGC 7733 (smaller, lower right) and NGC 7734 (larger, upper left). The third galaxy is currently referred to as NGC 7733N, and can actually be spotted in this picture if you look carefully at the upper arm of NGC 7733, where there is a visually notable knot-like structure, glowing with a different colour to the arm and obscured by dark dust.

Sharpening Our View of Climate Change with the Plankton, Aerosol, Cloud, ocean Ecosystem Satellite
As our planet warms, Earth’s ocean and atmosphere are changing.
Climate change has a lot of impact on the ocean, from sea level rise to marine heat waves to a loss of biodiversity. Meanwhile, greenhouse gases like carbon dioxide continue to warm our atmosphere.
NASA’s upcoming satellite, PACE, is soon to be on the case!
Set to launch on Feb. 6, 2024, the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission will help us better understand the complex systems driving the global changes that come with a warming climate.
Earth’s ocean is becoming greener due to climate change. PACE will see the ocean in more hues than ever before.
While a single phytoplankton typically can’t be seen with the naked eye, communities of trillions of phytoplankton, called blooms, can be seen from space. Blooms often take on a greenish tinge due to the pigments that phytoplankton (similar to plants on land) use to make energy through photosynthesis.
In a 2023 study, scientists found that portions of the ocean had turned greener because there were more chlorophyll-carrying phytoplankton. PACE has a hyperspectral sensor, the Ocean Color Instrument (OCI), that will be able to discern subtle shifts in hue. This will allow scientists to monitor changes in phytoplankton communities and ocean health overall due to climate change.
Phytoplankton play a key role in helping the ocean absorb carbon from the atmosphere. PACE will identify different phytoplankton species from space.
With PACE, scientists will be able to tell what phytoplankton communities are present – from space! Before, this could only be done by analyzing a sample of seawater.
Telling “who’s who” in a phytoplankton bloom is key because different phytoplankton play vastly different roles in aquatic ecosystems. They can fuel the food chain and draw down carbon dioxide from the atmosphere to photosynthesize. Some phytoplankton populations capture carbon as they die and sink to the deep ocean; others release the gas back into the atmosphere as they decay near the surface.
Studying these teeny tiny critters from space will help scientists learn how and where phytoplankton are affected by climate change, and how changes in these communities may affect other creatures and ocean ecosystems.
Climate models are one of our most powerful tools to understand how Earth is changing. PACE data will improve the data these models rely on.
The PACE mission will offer important insights on airborne particles of sea salt, smoke, human-made pollutants, and dust – collectively called aerosols – by observing how they interact with light.
With two instruments called polarimeters, SPEXone and HARP2, PACE will allow scientists to measure the size, composition, and abundance of these microscopic particles in our atmosphere. This information is crucial to figuring out how climate and air quality are changing.
PACE data will help scientists answer key climate questions, like how aerosols affect cloud formation or how ice clouds and liquid clouds differ.
It will also enable scientists to examine one of the trickiest components of climate change to model: how clouds and aerosols interact. Once PACE is operational, scientists can replace the estimates currently used to fill data gaps in climate models with measurements from the new satellite.
With a view of the whole planet every two days, PACE will track both microscopic organisms in the ocean and microscopic particles in the atmosphere. PACE’s unique view will help us learn more about the ways climate change is impacting our planet’s ocean and atmosphere.

Pumpkin space latte, anyone? ☕
Hubble captured this festive array of stars, Terzan 12, found in the Milky Way about 15,000 light-years from Earth. The stars in this cluster are bound together by gravity in a sphere-like shape and are shrouded in gas and dust. As the starlight travels through that gas and dust to Earth, blue light scatters, leaving the redder wavelengths to come through.

Happy Wednesday! It's time for an astronomy word of the day!
Asterism - an asterism is any prominent star pattern that isn’t a whole constellation, such as the Northern Cross or the Big Dipper (pictured below)

Imaged in luminance and photometric R, V and B filters. Approximately 2 hours total exposure time.
The Eagle nebula is a stellar nursery where new stars are born.
