Physics Majors Observe Longest Lunar Eclipse in Centuries

Physics Majors Observe Longest Lunar Eclipse in Centuries

In the very early morning of Friday November 19th, the full Moon slipped into the Earth’s shadow in an almost complete lunar eclipse, the longest in the century. This eclipse is particularly long because the Moon is at its farthest distance from the Earth on its elliptical orbit. During an eclipse, the Moon loses access to most of the sunlight that it usually reflects and can only reflect the small portion of redder light that bend around the Earth and through its atmosphere on the way to the Moon.

The four pictures below were taken by three physics majors. Connor McNeill (Class of 2024) and Michael Pedowitz (Class of 2024) took pictures that placed the lunar eclipse in the broader stellar context. In Connor’s picture, you can see Orion’s belt and sword to the left of the still relatively bright Moon (Fig. 1). Michael’s shows that the Moon was located right next to the Pleiades cluster, a set of seven bright stars that are sometimes called the Seven Sisters (Fig. 2).

Connor and Dean Klunk (Class of 2024) also took images of the Moon through a telescope. Connor used his own 3in telescope (Fig. 3), while Dean operated the physics department’s 11in telescope from the rooftop observatory (Fig. 4). The observatory is open to the students as well as the public on clear nights Mondays to Thursdays from 8pm to 10pm.

Fig. 3: The Moon taken through a 3in telescope during the maximum of the partial eclipse. The white edge to the upper right shows that the eclipse was not complete. The red color is the result of sunlight passing through the Earth’s atmosphere before reaching the Moon. Picture Credit: Connor McNeill

TCNJ Physics Faculty Dr. Shannon Graham Publishes Geophysics Article

TCNJ Physics Faculty Dr. Shannon Graham Publishes Geophysics Article

TCNJ Physics department professor Dr. Shannon Graham has recently published an article for the American Geophysical Union titled “A Global Set of Subduction Zone Earthquake Scenarios and Recurrence Intervals Inferred From Geodetically Constrained Block Models of Interseismic Coupling Distributions”. You can read the article in full by clicking on this link to the AGU official website. A brief summary of the research conducted for this article can be found below:

“In this study, we use results from a global tectonic and earthquake cycle model based on GPS measurements to estimate the locations and magnitudes of potential earthquakes on 16 of the world’s largest faults. Along these faults, two tectonic plates are coupled, or stuck together, to varying degrees causing the nearby portions of the plates to undergo distortion, which can be tracked using GPS. Studies of recent earthquakes suggest that slip occurred on the region of the fault that was stuck together prior to the earthquake. With this in mind, we use a model of global fault coupling to find regions where additional great earthquakes may occur. We suggest that nearly all of the world’s subduction zones, as well as the fault beneath the Himalayas, could produce a magnitude 9 or greater earthquake.”

TCNJ Physics Welcomes Dr. Daniel Capic as New HHMI Fellow

TCNJ Physics Welcomes Dr. Daniel Capic as New HHMI Fellow

Dr. Daniel Capic has officially joined TCNJ’s Department of Physics this fall as the HHMI Fellow and Visiting Professor of Physics.

Dr. Capic is a theoretical condensed matter physicist. His research involves the study of skyrmions,  which are quasiparticles that can appear in magnetic systems. Skyrmions have a non-trivial topology, as they appear as defects in the ferromagnetic order, which otherwise prefers the alignment of all magnetic spins in one direction. Skyrmions have a strong potential for computing applications since they can exist at the nanoscale, are easily created and manipulated, and are topologically protected. In addition to studying skyrmions and their properties, he is also interested in other topological quasiparticles that exist in magnetic systems, such as antiskyrmions and Hopfions.
Dr. Capic earned his PhD in theoretical condensed matter physics from the CUNY Graduate Center. While still a graduate student, he taught introductory physics courses at Lehman College. His current teaching interests are introductory physics courses and determining how to tailor them to a general undergraduate audience. He is interested in teaching courses focusing on magnetism in condensed matter systems in the near future.
Dr. Lanz tells us what we need to know about Thursday’s rare “Sunrise Scimitar”

Dr. Lanz tells us what we need to know about Thursday’s rare “Sunrise Scimitar”

If you’re in the tri-state area and look to the skies early on Thursday morning, June 10, you might notice something highly unusual — the rising sun will resemble a crescent moon.

Lauranne Lanz, assistant professor of physics, explains what you need to know about this quirky springtime sunrise.

1. Wait, what?

On June 10, we’ll get to see a partial solar eclipse, Lanz says. Solar eclipses happen when the moon passes in front of the sun from our perspective here on Earth. Partial eclipses happen when the moon is in front of only part of the sun at the start or end of the eclipse. In this case, 80 percent of the sun will be blocked by the moon.

2. It’s not annual — it’s annular.

Lanz explains that what’s happening on June 10 is actually an annular eclipse, which is a specific kind of solar eclipse. And this one is pretty rare, happening only twice in our area in the past 150 years.

“The moon’s orbit of the Earth is an ellipse — an oval — rather than a perfect circle, so sometimes it’s closer to the Earth and sometimes it’s further away,” she explains. “When it’s further away, it’s a little bit smaller than the sun in terms of how much of the sky each fills up, so at the moment of exact alignment, you can see a ring — an annulus — of the sun around the edges of the moon.”

3. Can I see it?

Kind of. On the east coast, we won’t see the full annular eclipse due to timing and alignment. But, we will be able to see the partial alignment that gives rise to a special sunrise described as a scimitar — a curved sword — as long as it’s not cloudy.

“It will be visible right at the east-northeast horizon at 5:32 a.m. and will gradually shift away from the sun and be gone by 6:30 a.m.,” Lanz says.

So set your alarms bright and early for this once-in-a-lifetime magical morning!
