Telescopes have enabled us to truly see the wonders of the Universe. Who invented them and how have they developed throughout history? Physics - Universe - Learning Points. The first optical telescopes were made around 1608. Early...

When light hits something, a number of things can happen: it can be reflected, refracted, diffracted or absorbed. But what does this mean? Physics - Waves - Learning Points. Manipulation of light is vital to our survival. Light waves...

The discovery by Robert Bunsen which allowed elements to be identified more easily, and even led to the discovery of new ones. Chemistry - Atoms And Bonding - Learning Points. Gustav Kirchoff assembled the first spectroscope - two...

When light emitted from a distant object reaches another object or opening, its waves are bounced or bent slightly around the object and interfere with each other to produce various patterns on whatever they ultimately fall on. For...

The Observatory on the Spanish island of La Palma is one of the world s leading centres for the study of astronomy, as it houses the 4.2m William Herschel telescope.

Dr. Forrester explains how scientists over the centuries have used a variety of tools to gaze into outer space.

This video explores the innovative use of telescopes mounted on Leicester University's Space Research Center to monitor pollution levels in the city of Leicester. By analyzing the quality of light affected by different pollutants, such...

A team of astronomers from Southampton University is leading a groundbreaking study on celestial black holes, focusing on the well-known Cygnus X1. Using massive telescopes in Spain and the Netherlands, they have discovered that this...

The historic Deep Impact space mission successfully collided a probe with Comet Temple One, revealing untouched core material for analysis by spacecraft and telescopes. This groundbreaking event offers humanity a glimpse into the...

Dr. Forrester examines the history of the telescope and discusses the parts of the telescope and the functions of each. She also explores different types of space technology such as the telescope, satellite, rocket, and space probe.

The James Webb Space Telescope (JWST) is a space-based observatory and the most powerful and advanced telescope ever launched into space. Named after the NASA administrator who pioneered the Apollo program, the Webb Space Telescope is...

SETI (Search for Extraterrestrial Intelligence) astronomer Jill Tarter describes how we use technology as a proxy for potential alien intelligence, and how our search involves looking for signals that nature doesn't make on her own.

Yes, it is theoretically possible to use telescopes to see if the moon landings were real, but practically no. It would take an incredibly powerful telescope to see signs of moon landings on the lunar surface, and even the best...

Sometimes, the acceptance of a lack of knowledge is far more valuable than conjecture. That being said, let’s talk about what we do know, because regardless, it is very weird.

What does ALMA stand for? Is it a huge telescope? Does the ALMA look for planets that might have life? What spectrum of light is difficult to observe? Why are there so many telescopes and why are they so big? Are antenna expensive? Where...

What are the different wavelengths of the electromagnetic spectrum? When seen, what can invisible light reveal? What discovers has the VLA found so far? How do astronomers spend their time?<br/>
The Very Large Array Telescope, Part 2

Looking forward to the James Webb Space Telescope? Just wait until ESO's Extremely Large Telescope (ELT) is completed.

Astronomers say they caught a glimpse of the biggest explosion in the cosmos ever observed by X-ray and radio telescopes. <br/>

As Earth makes its annual trip around the Sun, we feel the impacts of its journey in the form of seasons. Our planet’s tilt in relation to the Sun determines what season we experience here on Earth. But, did you know that the Sun goes...

Part 2 of the press conference announcing the first direct detection of gravitational waves -- February 11, 2016. The press conference continued after the live webcast concluded. See the remainder here for the first time.

In this third episode of a five-part series about NASA’s Laser Communications Relay Demonstration, we look at the LCRD flight payload, which launched on the U.S. Space Force’s Space Test Program Satellite-6 earlier on December 7.

At first glance, the bone-dry landscape of the Atacama Desert in Chile might seem inhospitable. But, it's prime real estate for astronomers. This desert is now home to the largest ground-based radio telescope in the world! The telescope...

The impact of comets on the surface of Jupiter are a fairly common experience. At the University of Central Florida, astronomers Joseph Harrington and Csaba Palotai are leading a project that studies precisely how these impacts happen,...
