    Irish Chronicles Document Links Between Volcanoes and Weather

    A study of over 40,000 written entries in Irish Annals and ice core measurements shows a strong correlation between the occurrence of volcanic eruptions and extreme cold weather in Ireland over a 1200 year period. Data analyzed in this study cover the period from 431 to 1649, during which time up to 48 volcanic eruptions are identified in Greenland ice core records through deposition of volcanic sulfate in annual layers of ice. You can find the study (open access), published on 6 June 2013 in IOP Publishing's journal Environmental Research Letters, at http://iopscience.iop.org/1748-9326/8/2/024035/article.

    EF-5 Tornado in El Reno, Oklahoma Widest Ever Recorded in US

    The EF-5 tornado that hit El Reno, Oklahoma on May 31st was the widest ever recorded in the US, according to the National Weather Service in Norman Oklahoma. The tornado, which remained on the ground for 40 minutes and reached 2.6 miles across (4.2 km), took the lives of 18 people including storm chasers Tim Samaras, Paul Samaras and Carl Young.

    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

In-depth questions and answers

1)What is the edge of the universe like? Will we be able to go past it someday?
2)Is it possible to travel through time?
3)Is there an object in the universe that can travel faster than the speed of light?
4)How much (in meters) is a black hole's diameter? What would happen if you got sucked into a black hole?
5)What is the biggest star discovered? And how big is that star?
6)How can a neutrino be detected?
7)What do you know about the 'Star of Bethlehem' that was mentioned in the New Testament of the Holy Bible?
8)Is there any uppermost temperature? Is it possible to measure the temperature in the core of a star?
9)If I wanted to become an astronomer, how would I go about doing that?
10)How do astronomers measure the distance to stars? Is it accurate?
11)What are Cepheid variables?
12)How does the ratio of the amounts of hydrogen to helium in a star affect what kind of star it is and what kind of light it gives off?
13)What is dark matter, and what are the problems with it?
14)Did the Big Bang create black holes?
15)What is the farthest thing I can see with my own eyes, and the farthest thing I can see with an amateur telescope, and the farthest-away thing the biggest telescopes on Earth can see?
16)What are the main differences between the sun and other stars?
17) How do people tell how old a star is?
18) How far across is the Milky Way? At a given time how can one locate the center of our galaxy as we orbit the Sun and the Sun orbits the galaxy? Is our solar system moving away from the center of the galaxy? How many years does it take the Sun to orbit the center of the galaxy? Specifically, where in the universe can our solar system be found?
