Every species on Earth has a fingerprint - whether or not they have fingers at all.

The Astrophysics Pioneers program is funding four innovative new missions that read like a best-hits album of the most exciting astronomical frontiers: from galaxy evolution and exoplanets, to neutron star mergers and astroparticle physics.

Sight, sound, and yes, taste, have all helped humanity better understand space, but what about smells? Scientists think we have a pretty good idea of what some places smell like, and decoding astronomical aromas can be a good way of...

Remember when astrophysicists thought they'd found signs of life on Venus? A different team re-crunched the numbers, and their results raised some questions about that claim. Also, a bunch of exoplanets are doing a really precise dance...

Driving can be dangerous, especially if you’re trying to juggle a variety of distractions while barreling down a busy highway. So scientists are looking into ways to keep us focused on the task at hand, even if you’re traveling in an...

You'd think that two planets with similar stats, orbits, and parent stars would grow up to be pretty similar, but these twins have atmospheres that beg to differ.

Not all of the naturally occurring elements were discovered here on Earth. Helium was discovered by examining sunlight, and that same technique is now teaching us about the composition of distant galaxies.

In order to understand how we study the universe, we need to talk a little bit about light. Light is a form of energy. Its wavelength tells us its energy and color. Spectroscopy allows us to analyze those colors and determine an object’s...

In this video Paul Andersen explains how the photons emitted from or absorbed by an atom or nuclei is directly related to electrons moving between energy level. Absorption and emission are a direct result of the conservation of energy....

Shot 7 times, yet the Harlan J Smith telescope at the McDonald Observatory still had 99% functionality. How?!

A technique that uses a prism to split the light coming off an object or atom.

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...

This video covers:

- What flame emission spectroscopy (also called flame photometry
) is.
- How it can be used to identify the metal ions present in
a sample
- How it shows the concentration of each metal ion...

A newly discovered “super-Earth” could offer scientists the best opportunity thus far to study the atmosphere of an exoplanet <br/>

We've learned about kinetics already, but how do we gather kinetic data? One clever method is by analyzing how the color of a solution changes over time, which is an indication of the concentration of certain compounds that interact with...

The Mars Curiosity rover has tested its laser and spectroscopy equipment on a 7cm rock dubbed 'Coronation'. The rover's ChemCam (Chemistry and Camera instrument) unit hit the rock with 30 pulses of infrared light over a 10-second period,...

Here is the sneak-peek of our latest video on UV - Vis Spectroscopy. It explains the importance of absorption spectroscopy. A brief idea about Ultra-violet and visible spectroscopy is also presented. It shows the light sources used for...

Scientists reflect on XMM-Newton’s 20th anniversary. The mission, led by ESA (European Space Agency), has dramatically improved our understanding of the cosmos thanks to detailed X-ray observations. NASA funded two of its three...

An international team of astronomers has developed a 3D model of a giant cloud ejected by the massive binary system Eta Carinae during its 19th century outburst. Eta Carinae lies about 7,500 light-years away in the southern...

The Cassini-Huygens mission arrived at Saturn in 2004, beginning an epic thirteen-year tour of the ringed planet and its many moons. Cassini and its companion probe, Huygens, were an international collaboration between NASA and...

The Second Servicing Mission, launched Feb. 11, 1997, greatly improved Hubble's productivity. The installation of new instruments extended Hubble's wavelength range into the near infrared for imaging and...

Astronomers using the Hubble Space Telescope have conducted the first spectroscopic survey of Earth-sized planets in the TRAPPIST-1 system's habitable zone. Hubble reveals that at least the inner five planets do not seem to...
