Top Study Tips from NASA

Study smarter this school year! We asked scientists, engineers, astronauts, and experts from across NASA about their favorite study tips – and they delivered. Here are a few of our favorites:

Study with friends

Find friends that are like-minded and work together to understand the material better. Trading ideas with a friend on how to tackle a problem can help you both strengthen your understanding.

Create a study environment

Find a quiet space or put on headphones so you can focus. You might not be able to get to the International Space Station yet, but a library, a study room, or a spot outside can be a good place to study. If it’s noisy around you, try using headphones to block out distractions.

Take breaks

Don’t burn yourself out! Take a break, go for a walk, get some water, and come back to it.

Wow, it really does look like a hummingbird!

Arp 142: The Hummingbird Galaxy Image Credit: NASA, ESA, Hubble, HLA; Processing & Copyright: Basudeb Chakrabarti

Explanation: What’s happening to this spiral galaxy? Just a few hundred million years ago, NGC 2936, the upper of the two large galaxies shown at the bottom, was likely a normal spiral galaxy – spinning, creating stars – and minding its own business. But then it got too close to the massive elliptical galaxy NGC 2937, just below, and took a turn. Sometimes dubbed the Hummingbird Galaxy for its iconic shape, NGC 2936 is not only being deflected but also being distorted by the close gravitational interaction. Behind filaments of dark interstellar dust, bright blue stars form the nose of the hummingbird, while the center of the spiral appears as an eye. Alternatively, the galaxy pair, together known as Arp 142, look to some like Porpoise or a penguin protecting an egg. The featured re-processed image showing Arp 142 in great detail was taken recently by the Hubble Space Telescope. Arp 142 lies about 300 million light years away toward the constellation of the Water Snake (Hydra). In a billion years or so the two galaxies will likely merge into one larger galaxy.

Hurry! You Can Catch a Ride to Jupiter with NASA

Well, at least your name can.  

One of the planet Jupiter’s largest and most intriguing moons is called Europa. Evidence hints that beneath its icy shell, Europa hides an ocean of liquid water – more water than all of Earth’s oceans combined. In 2024, our Europa Clipper robotic spacecraft sets sail to take a closer look…and when it launches, your name can physically be aboard! Here’s how: 

NASA’s Message in a Bottle campaign invites people around the world to sign their names to a poem written by the U.S. Poet Laureate, Ada Limón. The poem connects the two water worlds — Earth, yearning to reach out and understand what makes a world habitable, and Europa, waiting with secrets yet to be explored.

The poem will be engraved on Europa Clipper, along with participants' names that will be physically etched onto microchips mounted on the spacecraft. Together, the poem and names will travel 1.8 billion miles to the Jupiter system.

Signing up is easy! Just go to this site to sign your name to the poem and get on board. You can send your name en español, too. Envía tu nombre aquí.

The Europa Clipper launch window opens in October 2024, but don’t wait – everyone’s names need to be received this year so they can be loaded onto the spacecraft in time. Sign up by Dec. 31, 2023.

We hope you’ll be riding along with us! Follow the mission at europa.nasa.gov.

Many things in space stay the same for a human lifetime, but not the Bat Shadow. Hubble pictures taken 404 days apart show it “flapping” as the shadow changes position. It’s the result of a saddle-shaped disk: https://bit.ly/3Y5qu7W

Webb + Hubble > peanut butter + chocolate? We think so!

In this image of galaxy cluster MACS0416, the Hubble and James Webb space telescopes have united to create one of the most colorful views of the universe ever taken. Their combination of visible and infrared light yields vivid colors that give clues to the distances of galaxies (blue = close, red = far).

Looking at the combined data, scientists have spotted a sprinkling of sources that vary over time, including highly magnified supernovas and even individual stars billions of light-years away.

ALT TEXT: A field of galaxies on the black background of space. In the middle, stretching from left to right, is a collection of dozens of yellowish spiral and elliptical galaxies that form a foreground galaxy cluster. They form a rough, flat line along the center. Among them are distorted linear features, which mostly appear to follow invisible concentric circles curving around the center of the image. The linear features are created when the light of a background galaxy is bent and magnified through gravitational lensing. At center left, a particularly prominent example stretches vertically about three times the length of a nearby galaxy. A variety of brightly colored, red and blue galaxies of various shapes are scattered across the image, making it feel densely populated. Near the center are two tiny galaxies compared to the galaxy cluster: a very red edge-on spiral and a very blue face-on spiral, which provide a striking color contrast.

What is casting dark shadows across 36,000 light-years of space in this Hubble Space Telescope image?

The mysterious dark rays appearing to emanate from galaxy IC 5063 have intrigued astronomers, and there are a few different ideas about what is causing them. They could be like the shadows of clouds when light from the setting Sun pierces through them.

Astronomers have traced the rays back to the galaxy’s core, the location of an active supermassive black hole. One idea suggests that the shadows are being cast into space by an inner tube-shaped ring, or torus, of dusty material surrounding the black hole.

ALT TEXT: Rust-colored view of space, with a bright, narrow purple region at the center, a galaxy. Background stars and galaxies are scattered sparsely—this is a dusty rather than starry scene. To the upper left of the bright central region are dark dust lanes. Opposite these to the lower right, one dark area extends from the central bright region and splits into two dark rays. Similar dark rays can be seen to the top left, behind the dust lanes. The edges of the entire image are dark, fading from the colored center.

The Light, Dark, and Dusty Trifid Image Credit & Copyright: Robert Edelmaier and Gabriele Gegenbauer

Explanation: Messier 20, popularly known as the Trifid Nebula, lies about 5,000 light-years away toward the nebula rich constellation Sagittarius. A star forming region in the plane of our galaxy, the Trifid does illustrate three different types of astronomical nebulae; red emission nebulae dominated by light from hydrogen atoms, blue reflection nebulae produced by dust reflecting starlight, and dark nebulae where dense dust clouds appear in silhouette. The reddish emission region, roughly separated into three parts by obscuring dust lanes, is what lends the Trifid its popular name. The cosmic cloud complex is over 40 light-years across and would cover the area of a full moon on planet Earth’s sky. But the Trifid Nebula is too faint to be seen by the unaided eye. Over 75 hours of image data captured under dark night skies was used to create this stunning telescopic view.
