Flight Through the Orion Nebula in Visible and Infrared Light [Ultra HD]

Posted by

This visualization explores the Orion Nebula using both visible and infrared light. The sequence begins with a wide-field view of the sky showing the plane of our Milky Way Galaxy, then zooms down to the scale of the Orion Nebula. The visible light observation (from the Hubble Space Telescope) and the infrared light observation (from the Spitzer Space Telescope) are compared first in two-dimensional images, and then in three-dimensional models.

As the camera flies into the star-forming region, the sequence cross-fades back and forth between the visible and infrared views. The glowing gaseous landscape has been illuminated and carved by the high energy radiation and strong stellar winds from the massive hot stars in the central cluster. The infrared observations generally show cooler temperature gas at a deeper layer of the nebula that extends well beyond the visible image. In addition, the infrared showcases many faint stars that shine primarily at longer wavelengths. The higher resolution visible observations show finer details including the wispy bow shocks and tadpole-shaped proplyds. In this manner, the movie illustrates the contrasting features uncovered by multi-wavelength astronomy.

Olbers’ Paradox and Gravitational Light Deflection

Olbers’ Paradox and Gravitational Light Deflection
Kelsey Glazer, Towson University

A double dose of cosmic considerations, presented by the first undergraduate guest speaker in this series! Begin with the simple, yet deep, question of “why is the night sky dark?” This classic conundrum was raised two centuries ago because it directly conflicts the assumption of an infinite, eternal, and static universe. Then, probe further into last summer’s total solar eclipse. While the view of the Sun changed spectacularly, the rather subtle change in view of the stars behind the Sun reflected a grander geometric property rooted in gravity and the nature of space time. Join us for some delightful deliberations of our intriguing universe.

Host: Dr. Frank Summers

Recorded live on December 5, 2017 at the Space Telescope Science Institute in Baltimore, MD USA

Dropping an iPhone X Down 4000 FT Deep Hole! – What’s In There?

Posted by

So I dropped the new iPhone X down a 4000+ ft. deep mine hole and recorded it all to see what happens.

So here’s how my experiment went down. The fishing line I bought was 1329 yards (3987 ft.) When the line ran out I was pretty disappointed thinking it’s just dangling but the iPhone footage shows it seems to have hit something.

I assume the line just kept unraveling despite the phone landing, unless it just landed on a ledge or something and actually was 4000 feet deep? Hard to tell but after the initial 2-3 second drag delay, the iPhone was going down pretty fast and for like a good three minutes.
