How to Make a Box Pinhole Projector
Want to view a solar eclipse but don’t have eclipse glasses? No problem! An easy way to safely view a solar eclipse is with a box pinhole projector. With a few simple supplies, you can create a safe and fun way to experience the magic of an eclipse from anywhere. Watch this how-to video to see just how easy it is!
Except during the brief phase of totality during a total solar eclipse, you should never look directly at the Sun without proper eye protection specially designed for solar viewing. Do not use standard binoculars or telescopes to watch a solar eclipse without safe solar filters attached to the front of the device. Regular sunglasses are NOT safe for attempting to look directly at the Sun.

Where Are the Moon Rocks? We Asked a NASA Expert
Where are the Moon rocks from the Apollo missions kept? When they’re not being studied by institutions or enjoyed by museumgoers, NASA has a specialized Lunar Sample Curation Laboratory at NASA’s Johnson Space Center to store and keep these otherworldly samples safe. Studying these samples helps us learn more about the origin of not only our moon, but our planet. Deputy Apollo Sample Curator (Sept 2019 – Dec 2022) Dr. Juliane Gross explains more about lunar sample curation.

Neptune’s Disappearing Clouds Linked to the Solar Cycle
Recent observations from the Hubble Space Telescope show that Neptune's clouds are almost completely disappearing!
Astronomers report that their continual monitoring of Neptune’s weather uncovered a link between its shifting cloud abundance and the 11-year solar cycle, where the Sun’s activity waxes and wanes under the driving force of its entangled magnetic field.
At present, the cloud coverage seen on Neptune is extremely low, with the exception of some clouds hovering over the giant planet’s south pole. A team of astronomers discovered that the abundance of clouds normally seen at the icy giant’s mid-latitudes started to fade in 2019.

NASA Animation Sizes Up the Biggest Black Holes
Editor’s Note: A previous version of this video mislabeled the orbit of Saturn as the orbit of Jupiter.
This new NASA animation highlights the “super” in supermassive black holes. These monsters lurk in the centers of most big galaxies, including our own Milky Way, and contain between 100,000 and tens of billions of times more mass than our Sun.
Any light crossing the event horizon – the black hole’s point of no return – becomes trapped forever, and any light passing close to it is redirected by the black hole’s intense gravity. Together, these effects produce a “shadow” about twice the size of the black hole’s actual event horizon.
The animation shows 10 supersized black holes that occupy center stage in their host galaxies, including the Milky Way and M87, scaled by the sizes of their shadows. Starting near the Sun, the camera steadily pulls back to compare ever-larger black holes to different structures in our solar system.
First up is 1601+3113, a dwarf galaxy hosting a black hole packed with the mass of 100,000 Suns. The matter is so compressed that even the black hole’s shadow is smaller than our Sun.
The black hole at the heart of our own galaxy, called Sagittarius A* (pronounced ay-star), boasts the weight of 4.3 million Suns based on long-term tracking of stars in orbit around it. It’s shadow diameter spans about half that of Mercury’s orbit in our solar system.
The animation shows two monster black holes in the galaxy known as NGC 7727. Located about 1,600 light-years apart, one weighs 6 million solar masses and the other more than 150 million Suns. Astronomers say the pair will merge within the next 250 million years.
At the animation’s larger scale lies M87’s black hole, now with a updated mass of 5.4 billion Suns. Its shadow is so big that even a beam of light – traveling at 670 million mph (1 billion kph) – would take about two and a half days to cross it.
The movie ends with TON 618, one of a handful of extremely distant and massive black holes for which astronomers have direct measurements. This behemoth contains more than 60 billion solar masses, and it boasts a shadow so large that a beam of light would take weeks to traverse it.

Gravitational Waves: Ripples In Space-Time
Gravitational waves are invisible ripples in the fabric of space-time. They are caused by some of the most violent and energetic events in the universe.
These include colliding black holes, collapsing stellar cores, merging neutron stars or white dwarf stars, the wobble of neutron stars that are not perfect spheres and possibly even the remnants of gravitational radiation created by the birth of the universe.
In this video, Dr. Padi Boyd explains gravitational waves and how important Hubble is to exploring the mysteries of the universe.

What's Going on with the Hole in the Ozone Layer? We Asked a NASA Expert
What's going on with the hole in the ozone layer?
Thanks to a global effort to regulate ozone-depleting substances, the ozone hole is showing signs of recovery and is projected to return to a healthy level by mid-century.

Where Does Space Begin? We Asked a NASA Expert
Where does space begin? Well, it depends. There’s no sharp boundary that marks the end of atmosphere and beginning of space. But no matter where you draw the line in the sand — or the air — Earth’s atmosphere is full of all kinds of interesting stuff.
