It was the first satellite to orbit Earth
It is the brightest star in the night sky
Sirius
These types of waves have the lowest frequency and longest wavelengths in the electromagnetic spectrum
Radio Waves
This orbit is ~22,236 miles above the Earth's equator
Geostationary Orbit
What city is 101 Dalmations set in?
London
At a distance of ~167 AU, it is the furthest manmade object from Earth
Ursa Minor (Little Dipper)
This atmospheric layer is helpful for radio propagation on the ground, but less helpful when deflecting satellite signals from systems such as GPS
Ionosphere
Almost every large galaxy is thought to orbit one of these at their center
Supermassive Black Hole
It's the largest mammal in North America
Bison
Launched on October 14, 2024, this mission is the first attempt to study one of Jupiter's moons for evidence of a subsurface ocean
Europa Clipper
Stellar remnants after a star's death, these objects are famously dense: one teaspoon of its material has about 900 times the mass of the Great Pyramid of Giza
Neutron Star
This phenomenon explains the change in frequency of a wave in relation to an observer moving relative to the source.
Doppler Effect
An Areocentric orbit is an orbit around this celestial object
Mars
Officially, the Starbucks logo is not a mermaid but rather technically this
Siren
On December 24, 2024 it broke the the record for closest distance to the sun's surface for a manmade object at a cool 3.8 million miles.
Parker Solar Probe
It is the closest star to the sun, part of the Alpha Centauri system
Proxima Centauri
Telstar 1 was the first to perform a television broadcast and was owned by this company
AT&T
The James Webb Space Telescope is currently in solar orbit near the Sun-Earth equilibrium point designated L2. The L stands for this
Lagrange (or liberation)
Prestidigitator is another word for this
Magician
This was the first satellite to achieve orbit around Mars
Mariner 9
Considered "failed stars" at 13-80x the mass of Jupiter, these substellar objects can't fuse hydrogen into helium but can fuse deuterium and actually emit some light and heat
Brown Dwarf
In 1977, this narrowband radio signal was detected and remains possibly the strongest contender for a signal of extraterrestrial origin.
The Wow! Signal
This orbital maneuver is used to transfer a spacecraft between two orbits of different altitudes around a central body, ideally circular and coplanar
Hohmann (Orbital) Transfer
It's the national animal of Scotland
Unicorn
