Pinned post

👋 everyone! I wanted to take a moment and re-introduce myself.

I'm a queer space nerd (he/him) 🧑🏻‍🚀 searching for exoplanets 🌎 asteroids 🪨 & maybe even aliens 👽 with my backyard telescope 🔭

I'm also working towards a certificate in Astroimaging and Observatory Operation and post regularly about all things astronomy and space -- and about my 2 cats, Oliver and Ellie.

Happy to be here!

M92

Magnitude 6.4 globular cluster located 26,700 light-years away in the constellation Hercules. M92 is approaching us at 112 km/sec and was a "Polarissima Borealis", or "North Cluster", about 12,000 years ago (10,000 BC), and it will again in about 14,000 years (16,000 AD).

That. was. AWESOME!!

Here's a gif I created of the final few minutes to impact 🪨

What an incredible thing to have witnessed together in real time! Congrats @NASA @JHUAPL @ASI_spazio @LICIACube

@AsteroidDay

It's impact day! Less than 4 hours till impact (7:14pm EST)!

I'll be tuning in LIVE on both the official broadcast dart.jhuapl.edu

while also listening to some of my favorite scientists narrate in real-time on the @SETIInstitute channel

Did you know there will be a LIVE STREAM from the DRACO camera onboard DART as it comes in to impact the binary asteroid Dimorphos??

Get the links at dart.jhuapl.edu and follow along as humanity tests our ability to redirect asteroids🚀

#DARTMission #PlanetaryDefense #NASA

Didymos and Dimorphos are binary asteroids orbiting each other as they together orbit the sun.

We're impacting the smaller of the two, Dimorphos, to *slightly* change its orbit around Didymos.

A binary asteroid pair was chosen for this technology demonstration because it's a lot faster to measure the new orbital period of the smaller asteroid around the bigger one (it takes about half a day to orbit) than it would be to measure the change in orbit of a single asteroid around the sun (which takes years sometimes!)

Scientists have been studying this system for YEARS to make sure we know the current orbit really well!

So follow along and tune in later tonight as humanity tries to redirect an asteroid for the very first time!

Impact is at 7:14 PM EDT, with the onboard camera live stream starting at 5:30 PM EDT and the main event live stream starting at 6:00 PM EDT

We should get images up to a few *seconds* before impact! For this mission, a loss of signal is a GOOD thing 😉

M13

Located 25,000 light-years from Earth, M13 is by far the most famous sight in this part of the sky. It competes with M5 as the brightest globular cluster north of the celestial equator. The cluster contains some 500,000 stars with an age of 13 billion years, not much younger than the universe itself.

Kappa Herculis (Marsic)

This is a lovely, easy-to-split yellow-and-garnet-red double star. Despite their appearance, the two stars are not physically associated. The brighter 5th magnitude component of this optical double is 390 light years away, while the fainter 6th magnitude star is 470 light years distant.

Alpha Her - Rasalgethi

Alpha (α) Herculis is one of the best-known binary stars in Hercules. Also known as Rasalgethi (Arabic for “The Head of the Kneeler”), these stars take nearly 3,600 years to revolve around each other. The brighter star of alpha Herculis is an enormous red giant that’s 400 times the diameter of the Sun and some 800 times as bright. The pair have magnitudes of 3.5 and 5.4 roughly, and are some 380 light-years away.

#Ingenuity did it again!
The #MarsHelicopter flew its 33rd flight late in the afternoon on Sol 567, on a planned 111m path to the west, to reposition itself closer to the rover and the action 😀

95 Herculis

95 Herculis is a lesser known binary star in the Hercules constellation. At a distance of 470 light years, the pair is separated by 6 arc-seconds and shines at magnitude 4.8 and 5.2. While separately, the stars should appear white and yellow, their proximity tricks the eye into seeing more vivid color. Admiral Smythe, a prolific 19th century amateur astronomer, described the pair as “apple-green and cherry red”. What colors do you see?

DART asteroid-smashing mission on track for an impact Monday

NASA slamming a spacecraft into an asteroid 11 million km from Earth.

The agency's DART mission will impact with the asteroid moonlet Dimorphos on Monday (Sept. 26).

The DART mission is now hurtling through deep space toward the binary near-Earth asteroid Didymos and its moonlet Dimorphos. 

The mission is humanity's first attempt to determine if we could alter the course of an asteroid.

Dolidze 9

Dolidze 9 is an open cluster appearing in the constellation Cygnus. It is 3467 light years from our solar system. Its apparent size is approximately 5.0 arcminutes, corresponding to a physical diameter of 5 light-years.
