Kentucky Sky Talk: Traveling Through the Orion Nebula

This Sky Talk will be given by Prof C. R. "Bob" O'Dell of Vanderbilt University.  Bob was the project scientist who guided the development and construction of the Hubble Space Telescope and used it to make groundbreaking studies of the Orion Nebula.  The program will consist of a 40 minute Japanese National Television (NHK) documentary on Bob, HST, and his studies of Orion, followed by a question and answer period in which he will answer audience queries.

 

The MacAdam Student Observatory staff are pleased to welcome the public to our facility. We present a program of public outreach on the second Thursday of every month.  A 40-minute presentation on astronomy will be held  in  the Chemistry-Physics Building, before moving across the street to the observatory, weather permitting. Note that the temperature at the telescope is the same as it is outside. The Observatory is located on Parking Structure #2 on the University of Kentucky campus on this map.)

Parking Note: Guests for the monthly SkyTalk that bring vehicles should plan on leaving them in Parking Structure #2, next to the observatory. Visitors that park elsewhere are subject to citation. Some streets near the observatory will be closed due to construction intermittently over the next few years. These include Rose Street and Alumni Drive. The recommended path to Parking Structure #2 is outlined in red, here: Directions with street closures.pdf.

The Hayden Howard Lecture: Small Gaps Between Primes

The twin prime conjecture states that there are infinitely many pairs of distinct primes which differ by 2. Until recently this conjecture had seemed to be out of reach with current techniques. However, in 2013, it was proved that there are infinitely many pairs of distinct primes which differ by no more than B with B = 7 · 107 . Since then, the value of B has been considerably improved by others. In this talk we shall describe the basic ideas which lead to the proof of the above results. In particular, we shall discuss a breakthrough on the distribution of primes in arithmetic progressions which plays an important role in the proof.

 Refreshments will be served at 3:30 pm in room 745 of the Patterson Office Tower.
