Komeetta näyttäytyy -maaliskuun tähtitaivas Maaliskuussa tähtitaivas tarjoaa kiinnostavan, uuden vieraan. Eteläiseltä pallonpuoliskolta on nimittäin siirtynyt pohjoisen pallonpuoliskon tähtitaivasta ilahduttamaan PanSTARRS-komeetta C/2011 L4. Se näkyi eteläisellä taivaalla paljain silmin ja pohjoisellakin taivaalla sen uskotaan erottuvan hyvin paljain silmin pimeässä ja valosaasteettomassa paikassa, maalis-huhtikuussa. Planeetoista näkyvät maaliskuussa Jupiter, joka loistaa kirkkaimpana valopilkkuna jo illalla, ja aamuyöllä kaakon suunnalta taivaanrannasta nousee esiin Saturnus. Komeetta C/2011 L4 havaittiin ensimmäisen kerran kesäkuussa 2011 Hawaijilla sijaitsevalla teleskooppijärjestelmällä PanSTARRS. Komeetan arvioidaan näyttäytyvän nyt ensimmäistä kertaa maapallon lähettyvillä. Maaliskuun tähtitaivas kuunneltavana: Maaliskuun tähtitaivaalla näkyy komeettoja Maaliskuussa tähtitaivaan tarkkailijoita ilahduttaa mahdollisuus etsiä taivaalta komeetta, joka tulee näkyviin kuun puolivälin tienoilla.

Get Your Camera: Spectacular Comet Views Lighting Up the Night Sky | Wired Science A view of comet PANSTARRS from Argentina on March 2. Image courtesy Luis Argerich Sky-watchers in the Southern Hemisphere are currently being treated to the beautiful sight of comet PANSTARRS, which is visible to the naked eye in the early evening. They won’t be hogging all the fun, though, as the comet can be seen starting March 7 from the Northern Hemisphere. The comet, officially known as C/2011 L4, has been eagerly anticipated by amateur astronomers as it has approached the inner solar system. The icy ball was predicted to brighten significantly as the sun’s hot wind melted it, forming a long tail. PANSTARRS is named after the Hawaiian telescope where it was discovered in 2011. Two comets appear in this image, taken from Las Campanas observatory Chile in early March. On March 5, the comet will be at its closest approach to the Earth, being slightly farther than 1 astronomical unit, the distance between our planet and the sun.

Interactive graphic: Every active satellite orbiting earth Bob Dylan, a folk singer whose poetic lyrics defined his generation, has become the first musician to win the nobel prize for literature. The prize, which was first awarded in 1901, was presented to Dylan “for having created new poetic expressions within the great American song tradition,” according to an announcement from the Swedish Academy, which decides the prize each year from an undisclosed list of candidates. Dylan’s distinctive voice and his musicianship brought him early success. In 1965, he famously appalled folk fans by changing the sound they’d grown to love by playing electric guitar. Dylan is “a great sampler,” according to Sara Danils, permanent Secretary of the Swedish Academy, speaking to the Guardian newspaper. She said his 1966 album Blond on Blond was “An extraordinary example of his brilliant way of rhyming, putting together refrains, and his brilliant way of thinking.”

Asteroid impact mission targets Didymos / GSP / About Us / ESA Asteroid impact mission targets Didymos ESA’s AIDA mission now has a target: asteroid Didymos 22 February 2013 ESA’s proposed Asteroid Impact and Deflection Assessment mission now has a target: asteroid Didymos. The recent Russian meteor and, on the same day, our planet’s close encounter with an even larger chunk of celestial debris underline the need for us to learn more about these high-speed space rocks. For the last two years, ESA has been working with international partners on the mission concept, dubbed AIDA. Currently under study, the mission would intercept Didymos around the time of the asteroid’s closest approach to within 11 million km of Earth in 2022. Didymos is a ‘binary’, with two asteroids orbiting each other – one is roughly 800 m across, the other about 150 m. AIDA is a low-budget international effort that would send two small craft to intercept a double target. One effect would be a change in the orbital ballet of the two objects.

Lab 7: Future of the Forest Introduction The forests located in the mountains of southern Appalachia are typically lush and humid. Image Source: Southern Appalachian Forest Commission. As the climate changes, how will the forest change? In the western United States, will we see a return to grasslands and chaparral? In this lab, you'll view interactive graphics that show the predicted climatic conditions for the next 40 to 70 years under a variety of models and emissions scenarios. After completing this investigation, you should be able to: describe how the climate has changed in the recent past (since 1950) and how it is predicted to change in the future; and describe how tree (and plant) species distributions have changed in the past and are predicted to change in response to changing climate. Keeping Track of What You Learn In these pages, you'll find three kinds of questions.
