We hope you'll visit the Windows to the Universe web site many times this year! Total Lunar Eclipse on April 4th There will be a total lunar eclipse on April 4, 2105. This eclipse of the full moon will last less than five minutes, which makes it the shortest total lunar eclipse of the 21st century. This eclipse will be visible from eastern Asia, the Pacific, Australia, New Zealand, and western North America. See this EarthSky page for more detailed viewing information. I'm not sure what kind of flowers they might bring in May, but April does usher in one of the major meteor showers of the year - the Lyrids. If you spot any meteors on the night of April 22nd (into the morning of the 23rd), you will be carrying on a long tradition...for Chinese astronomers first observed Lyrid meteors more than 26 centuries ago! The moon sets in the early evening on April 22, which means a dark sky will make for optimal viewing for the 2015 Lyrids. Typically the Lyrids produce a meager 10-20 meteors per hour, though they sporadically generate large outbursts of 100 or more meteors per hour (as happened in 1803, 1922, 1945, and most recently in 1982). Look toward the shower's namesake, constellation Lyra, on the night of the 22nd (or any time from the 16th-25th when the shower could still be active) to catch a glimpse of a "falling star". April is a good month to talk about space exploration. On April 12, 1961, Russian cosmonaut Yuri Gagarin became the first person in space. He orbited the Earth once aboard the Vostok spacecraft. The flight lasted 1 hour and 48 minutes. 20 years later, on April 12, 1981, the first space shuttle Columbia was launched, with two crewmembers aboard - astronauts John W. Young and Robert L. Crippen. Columbia orbited the earth 36 times and returned to Earth on April 14. On April 24, 1990, space shuttle Discovery launched the Hubble Space Telescope into orbit. Since its launch, it has been responsible for many groundbreaking astronomical observations and has captured awesome images of the solar system, distant stars, and galaxies. In March 2013, NASA extended Hubble's science operations contract, so hopefully the telescope will be operating well into 2016!

New Desktop Application Has Potential to Increase Asteroid Detection, Now Available to Public A software application based on an algorithm created by a NASA challenge has the potential to increase the number of new asteroid discoveries by amateur astronomers and citizen scientists. Analysis of images taken of our solar system’s main belt asteroids between Mars and Jupiter using the algorithm showed a 15% increase in positive identification of new asteroids. “The Asteroid Grand Challenge is seeking non-traditional partnerships to bring the citizen science and space enthusiast community into NASA’s work,” said Jason Kessler, program executive for NASA’s Asteroid Grand Challenge. “The Asteroid Data Hunter challenge has been successful beyond our hopes, creating something that makes a tangible difference to asteroid hunting astronomers and highlights the possibility for more people to play a role in protecting our planet.” Astronomers find asteroids by taking images of the same place in the sky and looking for star-like objects that move between frames, an approach that has been used since before Pluto was discovered in 1930. With more telescopes scanning the sky, the ever-increasing volume of data makes it impossible for astronomers to verify each detection by hand. This new algorithm gives astronomers the ability to use computers to autonomously and rapidly check the images and determine which objects are suitable for follow up, which leads to finding more asteroids than previously possible. The desktop software application is free and can be used on any basic desktop or laptop computer. Amateur astronomers may take images from their telescopes and analyze them with the application. The application will tell the user whether a matching asteroid record exists and offer a way to report new findings to the Minor Planet Center, which then confirms and archives new discoveries. Thunderstorms and Tornadoes Becoming More Prevalent as Weather Warms This is a good time of year to explore the atmospheric conditions that create persistent squall lines that form over the U.S. central plains when cool, dry Canadian air masses collide with warm moist air from the Gulf of Mexico. Near the ocean, the Great Lakes, and mountains, uneven heating of land surfaces can produce spectacular afternoon thunderstorms announced by crackling thunder, life-threatening lightning, hail, tornadoes, and flash flooding. Sharing information about thunderstorm and tornado safety with your students is very important. The weather section of Windows to the Universe provides information about thunderstorms and tornadoes, explains how tornadoes form, and tells how meteorologists forecast when and where tornadoes will occur. In addition, our Tornado in a Bottle activity provides a great way to illustrate tornadoes for your students. Black Carbon - Background and a Classroom Activity Little particles in the atmosphere called aerosols may be small, but they have the ability to change climate. These tiny particles are a natural part of the atmosphere, coming from erupting volcanoes, sea salt, and wildfires. However, since the start of the Industrial Revolution, additional aerosols have been added to the atmosphere as fossil fuels are burned. Black carbon is the term that has been given to the product of the incomplete combustion of fossil fuels, biofuel, and biomass. It is commonly known as soot. Black carbon stays in the atmosphere for several days to weeks and then settles out onto the ground. Sources of black carbon are open biomass burning (forests and savannah burning that can start from natural causes like lightning or human-induced causes like slash and burn methods for clearing land), biofuel burning, diesel engines, industrial processes, and residential coal burning. Black carbon is produced around the world and the type of soot emissions vary by region. The amount (and type) of aerosols in the atmosphere has an impact on the albedo of our planet. Earth’s planetary albedo is about 0.31. That means that about a third of the solar radiation that gets to Earth is reflected out to space and about two thirds is absorbed. Aerosols like black carbon have a low albedo and reflect very little solar energy. This air pollution is having an impact on Earth’s climate. Scientists Ramanathan and Carmichael estimate that black carbon emissions are the second largest contributor to global warming, after carbon dioxide emissions. Reducing black carbon emissions is one of the fastest strategies for slowing global warming. Luckily, many policies have been put in place to reduce the production of black carbon around the world, and the technology necessary to lessen black carbon emissions already exists. To improve further, we need to better regulate the industrial processes that produce black carbon, and individuals need affordable and available technology to be able to make shifts away from practices like biofuel cooking and residential coal combustion that are still used in much of the world today. The importance of black carbon's role in global warming has come to the forefront of the minds of many concerned citizens and exciting steps are already being taken to address issues like making cleaner burning cook stoves available in developing nations. These reductions of black carbon around the world will not only aid in reducing global warming, but will improve human health and environmental aesthetics. Try out the Changing Planet Activity called Black Carbon - A Dusty Situation to teach about black carbon in your classroom. Many teachers present their weather unit in the spring. You can't teach about weather until you have talked about clouds! Do you talk to your class about the 'ingredients' needed to make clouds? Cloud physics is extremely complicated and scientists are researching that area every day. Fundamentally though, you do need three main ingredients to create a cloud - water, CCN, and a drop in pressure. Cloud Condensation Nuclei (CCN) are vitally important in this 'recipe'! When water in the vapor form experiences a drop in pressure, it wants to condense, but it needs a surface on which to condense. That's where the CCN come in. A CCN can be a speck of dirt, dust, pollen, or even a piece of human skin or hair. Do you know what the most common CCN is? It's tiny bits of sea salt released in sea spray. It makes sense when you think about how much of the Earth is covered with ocean water. We have an activity on the site called the Three Clouds Activity. It will reinforce these concepts nicely. The Cloud in a Bottle part comes with a great Student Activity Sheet that you are welcome to use in your classroom. Calendar of EventsApril is National Garden Month Every April, communities, organizations, and individuals nationwide celebrate gardening during National Garden Month.

The National Oceanic and Atmospheric Administration invites you to help scientists track the movements of endangered humpback whales between NOAA’s Stellwagen Bank National Marine Sanctuary and its sister sanctuaries across the Caribbean as part of Carib Tails, an international citizen science effort. By photographing the tails of humpbacks they encounter at sea, boaters can support on-going research to collect migration data on the shared population of approximately 1,000 humpbacks. Photographs will be matched to entries in the North Atlantic Humpback Whale Catalog and images of previously unknown and unphotographed whales will be added to the collection. A dedicated website provides tips on how to photograph flukes for research purposes, photo submission forms and other information about humpback whales. Researchers identify individual humpback whales by the black and white patterns on the underside of their flukes (tails). Scars and natural pigmentation, ranging from all white to all black, along with the scalloped shaped edge of the tail, give each whale a distinct identification. Photographs of humpback flukes have allowed researchers to monitor the movements, health and behavior of individual animals since this research began in the 1970's. Read more about the program at the Carib Tails website. Sea Turtles and the Quest to Nest Sea Turtles and the Quest to Nest, a game developed by NOAA's National Marine Fisheries Service and the National Ocean Service, is designed to help students understand how they can help protect turtles and their habitats. The game takes place in the southeastern U.S. Students are introduced to all of the people and animals that play a role in the life of loggerhead turtles.
