Mars’ Olympus Mons is biiiiig. 🗻

This simulated view shows our own Mt. Everest compared to Olympus Mons, the colossal shield volcano on Mars.

Everest, Earth’s largest peak is around 9 km high, less than half the height of Olympus Mons which extends to 21.9 kilometers above the Martian surface. Olympus Mons would just fit within the borders of France (or the US state of New Mexico) as its diameter is roughly 600 kilometers. This view shows just how big that is! Hard to comprehend without our virtual spaceship.

Happy 4th! 🎆

We set up a fireworks show for Perseverance Rover and Ingenuity of @nasajpl to watch from Jezero Crater as the sun sets in the distance. We hope you’re enjoying your independence little robots!

What’s real and what’s not:

The topography data is @uahirise surface data of Mars inside Jezero Crater.

The fireworks are just pretend, based on OpenGL shader inspired by BigWings/The_ArtOfCode‬ - thx! (probably not enough oxygen in the the martian atmosphere to even have regular combustion based fireworks)

Audio is real fireworks audio processed to simulate what they might sounds like in a Martian atmosphere by Nasa’s Sounds of Mars page: https://mars.nasa.gov/mars2020/participate/sounds/?voice=true

Vintage Powerpoints - Eclipses

Did you know, before the days of smart boards and power points, and even over head projectors, teachers and professors used custom made glass slides to show diagrams and figures during class. Each one was hand made and meant to last for decades. Ours have lasted over a century!

We happen to have a few thousand lying around the basement.

Here are a few regarding eclipses, probably used to teach an astronomy or physics class over a hundred years ago.

Oh yeah, Annular Eclipse coming Thursday, June 10th…

Big thanks to @erica_shires for getting these scanned in and initiating the digitization project. They might last another hundred years, but only if they stay hidden in their boxes.

Slide #1: Total Eclipse August 7th 1869
Slide #2: Schematic diagram showing Earth’s umbra
Slide #3: Stage of total solar eclipse from Jan 24, 1925
Slide #4: Undated Annular Eclipse
Slide #5: The Saros Cycle of Eclipses
Slide #6: Predicted Solar Eclipses from 1919 to 1940.

Happy International Astronomy Day

May 15, 2021 is International Astronomy Day (or just Astronomy Day given the a-geopolitical nature of space).

Cosmic Pinball

Some cosmic pinball featuring Voyager 2, as it gets bounced around the solar system. During its first decade or so, Voyager 2 met Jupiter, Saturn, Uranus, and Neptune for close up encounters. Its trajectory was altered by the gravitational fields of these gas and ice giants. You can see the effect in this simulation showing the path of the spacecraft over a few dozen years.

We wish we could invite all the #newstudents, faculty and staff down to the dome for a show this week. Looks like it will have to wait... stay tuned though. As soon as we can, we'll open our doors, close the hatch, and fly you to the moon! Here's a flyby of @ccnycitycollege for now.

51 years ago today #apollo11 landed on the moon. It took some serious skills to find a good spot. Here are the last few minutes of the flight showing the trajectory of the lunar lander as Neil Armstrong gracefully guides it down to the surface.

Happy ‪#4thofJuly2020‬ . We've decided to skip the local ‪#nycfireworks‬ show and head to Tycho Crater, on the ‪#moon‬. It's a lot quieter and there is plenty of @openspaceproj .

Next year? Europa maybe?

Today’s #solareclipse will cast a shadow over parts of Africa and Asia. To bad we can’t be there in person to witness. Here’s what it might be like from a few thousand km above the earth. #eclipse #astronomy #2020 has some ok things no? #solareclipse2020

Enjoy this peaceful view (simulated of course) from the cupola of the @iss as it makes a pass over #NYC.

It's looking like clouds might get in the way of tonight's #manhattanhenge. Here's our last simulated #sunset, providing you with a virtual helicopter ride up the East River, looking West across #NYC. All done with #opendata.

05/28/2020

What if you managed to catch a picture perfect sunset everyday of the year? That would take some dedication. Here's a quick version of the setting sun over #NYC every day during 2020. Note the #manhattanhenge days around the end of May and early July.

#nycastronomy #sciviz #nyc #sunset #space #astronomy

05/25/2020

Coming this week to #nyc ...
#manhattanhenge . On May 29, sunset will line up with the nyc street grid.

We probably won’t attend in person so we’ve done the next best thing.

Using #nycopendata and @openspaceproj , we can visualize this event without leaving the house. ☹️/😊

Enjoy. More views to come throughout the week.

Four Moons of Jupiter and a Four Part Fugue

We're not doing any live shows right now (duh). Instead, if you need to relax and voyage outside your apt, here's the next best thing: our new YouTube Channel, where we'll post videos, like this one, which features the moons of Jupiter and music by Bach:

Feeling a little constrained of late? Sorry we can’t transport you to far away lands right now. Did you know however, that you (and whoever happens to be around the house) can take your own trips around the cosmos? The software we use in the planetarium is free and open source: check out @openspaceproj for more. If you have a gaming quality machine you should be able to run it just fine.

What if you could see in Xrays? Or infrared? Or maybe the 21 cm line emitted by changes in energy of neutral hydrogen atoms? Ans: it would look gorgeous!! We’re adding some more all-sky maps so we can see how the sky looks in different wavelengths of light.

Well done Mercury! We had a great viewing of the transit all morning. Our astrophotography leaves something do be desired (yes that little smudge in the middle of the sun is Mercury). But we made up for it with great company and good weather. Even public safety swung by to make sure the planets were all adhering to Kepler’s Laws! @ The City College of New York

11/07/2019

If the skies are nice on the morning of the 11th, join us in front of the NAC building to do what you were always told not to do: stare at the sun! We’ll set up the solar telescope and try to catch a glimpse of the #mercurytransit 2019. Next transit is not going to happen until 2032. (And you’re supposed to graduate by then aren’t you)

The CCNY Planetarium

First installed in 1973-74, the CCNY Planetarium in the Marshak Science Building has seen decades of action bringing crystal clear night skies to the locals of Hamilton Heights as well as the greater NYC metropolitan region. Its use has fluctuated over the years, however we are currently taking steps to bring the planetarium back to life by adding some modern technologies to the room. We’ll compliment the existing Spitz 512 analog instrument with digital projections and theatre quality audio. During the first half of 2018, we plan to begin offering shows again for CCNY students. After we iron out the wrinkles, we hope to expand our invitations to local neighborhoods and schools as well. In the meantime, follow us here on FB or Instagram (ccnyplanetarium) to hear about updates and announcements.
