The Dark Universe: Exploring the Euclid Mission with Jason Rhodes

What are dark energy and dark matter? Neil deGrasse Tyson and comedian Chuck Nice learn about the Euclid Mission and our latest efforts to uncover the secrets of The Dark Universe with JPL Researcher, Jason Rhodes.

This artist impression shows Euclid leaving Earth and on its way to Sun-Earth Lagrange point L2. This equilibrium point of the Sun-Earth system is located 1.5 million kilometres from Earth in the opposite direction of the Sun. L2 revolves around the Sun along with Earth. During Euclid’s orbit at L2, Euclid’s sunshield always blocks the light from the Sun, Earth and Moon while pointing its telescope towards deep space, ensuring a high level of stability for its instruments.

OSIRIS-REx & Asteroid Mining with Natalie Starkey

Will an asteroid hit Earth in 2182? Neil deGrasse Tyson and comedian Chuck Nice learn about asteroid mining, OSIRIS-REx sample-return, and the origins of life with cosmochemist Natalie Starkey.

OSIRIS-REx will be the first U.S. mission to carry samples from an asteroid back to Earth. In 2019, OSIRIS-Rex will approach asteroid 1999 RQ36, or “Bennu,” and begin to map the asteroid’s surface to select a sample site. Upon collecting a sample, OSIRIS-Rex will return to Earth in 2023.

Physics & Philosophy with Sean Carroll

Why is the past different from the future? Neil deGrasse Tyson and Chuck Nice explore the universe’s deepest questions like why is there anything, what is the present, if there could be a unified theory of physics with theoretical physicist Sean Carroll.

This new infrared view of the star formation region Messier 8, often called the Lagoon Nebula, was captured by the VISTA telescope at ESO’s Paranal Observatory in Chile. This colour picture was created from images taken through J, H and Ks near-infrared filters, and which were acquired as part of a huge survey of the central parts of the Milky Way. The field of view is about 34 by 15 arcminutes.

Cosmic Queries – Cosmological Curiosities

What is nothing? Does nothing exist? Neil deGrasse Tyson and comedian Chuck Nice explore cosmological curiosities about the end of the universe, dark matter, and more!

This false-color mosaic of the central region of the Coma cluster combines infrared and visible-light images to reveal thousands of faint objects (green). Follow-up observations showed that many of these objects, which appear here as faint green smudges, are dwarf galaxies belonging to the cluster. Two large elliptical galaxies, NGC 4889 and NGC 4874, dominate the cluster's center. The mosaic combines visible-light data from the Sloan Digital Sky Survey (color coded blue) with long- and short-wavelength infrared views (red and green, respectively) from NASA's Spitzer Space Telescop
