¶Mars colonization

Musk is a douchebag and a KSR ripoff
* "To get around the problem, in 2017 Musk proposed solar storm shelters on the ships designed to double up as the first habitats"
* "Musk has repeatedly mooted a plan to heat up the planet and release stored carbon dioxide, citing a 1993 research paper as evidence it would work. He claims doing so would enable humans to walk around Mars with just a breathing apparatus."

    *DO* CUT TREES FOR WOOD
Otherwise:
    they will never dry & will sizzle when burned

WHERE CAN IT BE SEEN


HOW TO OBSERVE
* check space weather:
    → 🔗doomsday
* go out to a dark place
* look north, between 22-2am:
    "The best time to observe the northern lights is around midnight, when the auroral oval is typically farthest south and the sky is darkest."
    "4. Timing: Between 10pm and 2am local time is usually the best time to spot auroras, the prediction center said."
* """“Cellphones are much better than our eyes at capturing light,” Brent Gordon, chief of NOAA’s Space Weather Services Branch, said in a news conference Friday. “Just go out your back door and take a picture with a newer cellphone, and you’d be amazed at what you see in that picture versus what you see with your eyes.”"""

¶Magnitude

https://en.wikipedia.org/wiki/Magnitude_(astronomy)
"""
The scale is logarithmic and defined such that a magnitude 1 star is exactly 100 times brighter than a magnitude 6 star.
"""

"""
The Sun has an apparent magnitude of −27
and Sirius, the brightest visible star in the night sky, −1.46.
Venus at its brightest is -5.
The International Space Station (ISS) sometimes reaches a magnitude of −6. 
"""

"""
Full Moon: Approximately -12.6 to -13.6 (very bright).
Venus: Brightest planet, around -4.6 (can reach up to -4.9).
Jupiter: Around -2.0 (very bright).
Mars: Varies, but typically around +1.0 to -2.0 depending on its distance from Earth.
Saturn: Approximately +0.5 (moderately bright).
"""

Stars in Orion:
    Betelgeuse: Around +0.5 (a red supergiant star).
    Rigel: Approximately +0.1 (a blue supergiant star).
    Bellatrix: About +1.6 (a blue giant star).
    Saiph: Roughly +2.1 (a blue supergiant star).

Notable Comets:
    Comet Hale-Bopp (1997): Reached a magnitude of -1.0 at its brightest.
    Comet NEOWISE (C/2020 F3): Reached about +0.7 at peak brightness.

Blue Star: Sirius (Alpha Canis Majoris) - Magnitude: -1.46
White Star: Vega (Alpha Lyrae) - Magnitude: +0.03
Yellow Star: Capella (Alpha Aurigae) - Magnitude: +0.08
Orange Star: Arcturus (Alpha Boötis) - Magnitude: -0.05
Red Star: Betelgeuse (Alpha Orionis) - Magnitude: Approximately +0.5

¶"Alyoshenka" baby, alien conspiracy (1996)

https://en.wikipedia.org/wiki/Alyoshenka
"""
Alyoshenka (Russian: Алёшенька, diminutive of the Russian male first name Alexey) or the Kyshtym Dwarf is believed by many to be a prematurely born female baby with many deformities found in the village of Kaolinovy, near Kyshtym, Chelyabinsk Oblast, Russia in May 1996. Subsequently, the remains were lost and only photos and videos survive. Various supernatural explanations arose.

¶[!!**] try celestia
(via old note)

"""
Celestia is a 3D astronomy software that allows you to explore the universe in real-time. Unlike Stellarium, which focuses on simulating the night sky as seen from Earth, Celestia lets you travel freely through space to visit stars, planets, moons, galaxies, and other celestial objects. You can explore from any point in space, view objects at different scales, and even travel through time to observe how the positions of celestial bodies change. It’s an open-source program known for its educational value and customizable features through add-ons, such as detailed models of planets and spacecraft.
