This photo provided by NASA. Expedition 64 crew member NASA astronaut Kate Rubins, is seen during Soyuz qualification exams Wednesday, Sept. 23, 2020 at the Gagarin Cosmonaut Training Center (GCTC) in Star City, Russia. Rubins told The Associated Press on Friday, Sept. 25 that she plans to cast her next vote from space – more than 200 miles above Earth. Rubins and two Russian cosmonauts are preparing for a mid-October launch to the International Space Station, where she’ll spend the next six months. (Andrey Shelepin/GCTC/NASA via AP)

This image released Wednesday, April 10, 2019, by Event Horizon Telescope shows a black hole. Scientists revealed the first image ever made of a black hole after assembling data gathered by a network of radio telescopes around the world.

SpaceX's plans to leave Earth's orbit start with this shiny creation. Starship is the next-gen spaceship that could one day deploy satellites, carry artists around the moon and even touch down on the moon and Mars. SpaceX founder Elon Musk tweeted this look at a stainless-steel Starship prototype in Texas on Jan. 10, 2019. This version wasn't intended for orbital duty, but was used as a "hopper" to test takeoffs and landings. "Starship will look like liquid silver," Musk tweeted in late 2018. SpaceX is working on an orbital prototype in Texas. The new Starship is meant to launch into Earth orbit. Originally published Jan. 28, 2019, and updated with new Starship milestones.

Ice shelves in Antarctica, such as the Getz Ice Shelf seen here, are sensitive to warming ocean temperatures. Ocean and atmospheric conditions are some of the drivers of ice sheet loss that scientists considered in a new study estimating additional global sea level rise by 2100. Credits: Jeremy Harbeck/NASA

Left: false RGB stacked Chandra/ACIS-S image of the Whirlpool Galaxy, M 51 (total exposure of ≈850 ks). Colored points are XRSs: Red is 0.3-1 keV; green is 1-2 keV; blue is 2-7 keV. M 51-ULS1 is the orange source at the center of the 60'' × 60'' dashed white box. Diffuse emission is from hot gas. Right: HST image of the area defined by the white box in the top image. Red is the F814W band; green is F555W; blue is F435W. The magenta circle marks the X-ray position of M 51-ULS, which lies at the edge of a young star cluster. The source is located at right ascension and declination 13:29:43.30, +47:11:34.7, respectively. Credit: arXiv:2009.08987 [astro-ph.HE]

The n-helium-3 precision experiment, conducted at ORNL, measured the weak force between protons and neutrons by detecting the tiny electrical signal produced when a neutron and a helium-3 nucleus combine and then decay as they move through the helium gas target cell.

Scanning tunneling microscope image of wide-band metallic graphene nanoribbon (GNR). Each cluster of protrusions corresponds to a singly-occupied electron orbital. The formation of a pentagonal ring near each cluster leads to a more than tenfold increase in the conductivity of metallic GNRs. The GNR backbone has a width of 1.6 nanometers.

The incoming signal (red, lower left) proceeds through a beam splitter to the photon detector, which has an attached time register (top right). The receiver sends the reference beam to the beam splitter to cancel the incoming pulse so that no light is detected. If even one photon is detected, it means that the receiver used an incorrect reference beam, which needs to be adjusted. The receiver uses exact times of photon detection to arrive at the right adjustment with fewer guesses. The combination of recorded detection times and the history of reference beam frequencies are used to find the frequency of the incoming signal. Credit: NIST
