August 2019: Picture of the Month

This picture is an original photograph of the Perseid meteor shower taken by ASX Chief Graphic Designer Hansen Jiang. The photo was created by superimposing separate pictures of two meteors onto each other, which is why two streaks of light can be seen.

The Perseids meteor shower is visible from late July to mid August. It is caused by dust particles ejected from the Swift-Tuttle comet, which orbits the sun every 133 years. These particles cross paths with the Earth, and produce short, bright streaks of light as they burn up in the atmosphere.

May 2019: Picture of the Month

On May 11th, ASX participated in Science Rendezvous, along with many other science departments and organizations at U of T to bring science out of the lab and onto the street. Our booth included a demonstration of the principles of general relativity, using a sretched out piece of fabric, some counters and marbles. The heavier the object on the fabric, the more it influenced the movements of other objects. The principle of inflation was also demonstrated, using balloons decorated with stars. As the balloons were inflated, stars moved farther apart, which is consistent with our observations.

As per tradition, execs donned ceremonial ASX garb, including space suits and cosmic squid hats.

Why is there a large boulder near the center of Tycho’s peak? Tycho crater on the Moon is one of the easiest features to see, visible even to the unaided eye (inset, lower right). But at the center of Tycho (inset, upper left) is a something unusual — a 120-meter boulder. This boulder was imaged at very high resolution at sunrise, over the past decade, by the Moon-circling Lunar Reconnaissance Orbiter (LRO). The leading origin hypothesis is that that the boulder was thrown during the tremendous collision that formed Tycho crater about 110 million years ago, and by chance came back down right near the center of the newly-formed central mountain. Over the next billion years meteor impacts and moonquakes should slowly degrade Tycho’s center, likely causing the central boulder to tumble 2000 meters down to the crater floor and disintegrate.

From our vantage point in the Milky Way Galaxy, we see NGC 3344 face-on. Nearly 40,000 light-years across, the big, beautiful spiral galaxy is located just 20 million light-years away in the constellation of Leo Minor. This multi-color Hubble Space Telescope close-up of NGC 3344 includes remarkable details from near infrared to ultraviolet wavelengths. The frame extends some 15,000 light-years across the spiral’s central regions. From the core outward, the galaxy’s colors change from the yellowish light of old stars in the center to young blue star clusters and reddish star forming regions along the loose, fragmented spiral arms. Of course, the bright stars with a spiky appearance are in front of NGC 3344 and lie well within our own Milky Way.

Colourful star trails arc through the night in this wide-angle mountain and skyscape. From a rotating planet, the digitally added consecutive exposures were made with a camera fixed to a tripod and looking south, over northern Iran’s Alborz Mountain range. The stars trace concentric arcs around the planet’s south celestial pole, below the scene’s rugged horizon. Combined, the many short exposures also bring out the pretty star colours. Bluish trails are from stars hotter than our Sun, while yellowish trails are from cooler stars. Near the center, the remarkably pinkish trail was traced by the star-forming Orion Nebula.
