NASA’s Hubble Space Telescope has determined the size of the largest icy comet nucleus ever found. And, it’s big! With a diameter of approximately 80 miles across, it’s about 50 times larger than typical comets. Its...

In this video, we explore the concept of how telescopes allow us to see objects that are light years away, giving us a glimpse into the past. By understanding how light reflects off objects and travels to our eyes, we can comprehend how...

Europe experienced one of the most remarkable periods in history roughly between 1550 and 1700, when three of history's most important events were occurring simultaneously: the Renaissance, the Reformation, and the Scientific Revolution....

On April 29, 2009, a five-second-long burst of gamma rays from the constellation Canes Venatici triggered the Burst Alert Telescope on NASA's Swift satellite. As with most gamma-ray bursts, this one -- now designated GRB 090429B...

The Hubble Space Telescope has been revealing the secrets of the universe for over 30 years, but it turns out Hubble has some secrets of its own!



The question is: When was the last...

Astronomers have found the best evidence for a black hole of an elusive class known as “intermediate-mass,”...

30 years ago, the Hubble Space Telescope unlocked a window on the universe. Through that window we’ve seen the wonders of our Milky Way and expanded our vision across the galaxy. From the birth and death of stars to the...

What is OPAL?



OPAL (Outer Planet Atmospheres Legacy) is a project to obtain long time baseline observations of the outer planets in order to understand their atmospheric dynamics and evolution as...

It about the optical devices-the eye, telescope, image beyond 2F length, image at infinity and telescope.

Asteroids, comets, and meteors: what's the difference? These space rocks each have their own unique attributes. But differences aside, these fascinating objects are all worthy of study. Just ask @NASA Jet Propulsion Laboratory...

The Hubble Space Telescope is keeping watch over many, many galaxies using the combined superpowers of its incredible optics and a quirk of nature called gravitational lensing.

The world's largest digital camera is currently being assembled at a warehouse in California. We caught the short window of time to see the camera's massive lens.

You’ve probably seen beautiful images of space taken from telescopes around the world and out in orbit. But how does a bunch of intergalactic information become a vibrant photograph? And what else can we see, feel, and hear from that...

Satellite footage, telescopic photos and animation are used to teach students about the many fascinating aspects of our solar system. Viewers are introduced to ancient astronomers, telescopes, observatories and space exploration....

A brief history of geocentric and heliocentric solar system models are discussed. Kepler's first law is defined. How to draw an ellipse is demonstrated. Planet eccentricities are discussed. This is an AP Physics C: Mechanics...

Over the years, the Hubble Space Telescope has taken hundreds of images of different kinds of incredible nebulae in our universe.

A nebula is a giant cloud of dust and gas in space. There are...

Our solar system is full of incredible objects, and some of them are manmade! Beyond the probes we've sent to observe other planets, we've put countless objects up into orbit to perform a variety of functions. What are these, where are...

Servicing Mission 3B was actually the fourth visit to Hubble. NASA split the original Servicing Mission 3 into two parts and conducted 3A in December of 1999. During SM3B a new science instrument would...

The Hubble Space Telescope is more well known for its picturesque views of nebulae and galaxies, but it's also useful for studying our own planets, including Mars.



Hubble imaged Mars on May 12, 2016 - ten days...

Exploring the mysteries of dark energy and black holes. Identifying exoplanets. Capturing the origins of galaxies. Just some of what's happening at ground-based observatories -- windows on the universe that allow researchers to gaze...

A rocket scientist talks about why she finds her career so exciting in this video for secondary PSHE or science students. Dr. Maggie Aderin explains where her passion for space comes from and talks about the learning difficulties she has...

In a wafer, what are the limits to glass and what is a possible solution?<br/>
Magical Glass Technology, Part 2

The $10 billion James Webb Space Telescope has safely arrived at Lagrange Point 2 — and it’s now getting ready to look back in time to 13.7 billion years ago.

So we've made it all the way to the 20th century with the history of astronomy. Plenty had to happen to get us to that point, but the most amazing stuff is yet to come! Shortly after Einstein did his best work, a guy named Edwin Hubble...
