Astronomy picture of the day - 2016 April 25 - Supernova Remnant Simeis 147: The Spaghetti Nebula
Image Credit & Copyright: Giuseppe Donatiello (Italy) and Tim Stone (USA)
Explanation: It's easy to get lost following the intricate strands of the Spaghetti Nebula. A supernova remnant cataloged as Simeis 147 and Sh2-240, the glowing gas filaments cover nearly 3 degrees -- 6 full moons -- on the sky. That's about 150 light-years at the stellar debris cloud's estimated distance of 3,000 light-years. This sharp composite includes image data taken through a narrow-band filter to highlight emission from hydrogen atoms tracing theshocked, glowing gas. The supernova remnant has an estimated age of about 40,000 years, meaning light from the massive stellar explosion first reached Earth about 40,000 years ago. But the expanding remnant is not the onlyaftermath. The cosmic catastrophe also left behind a spinning neutron star or pulsar, all that remains of the original star's core.
Imagens do Mundo - Portugal - A Revolução dos Cravos
25 de Abril de 1974, uma data marcante para o Povo Português, que assistiu a uma mudança de regime. Através do MFA (Movimento das Forças Armadas) a Ditadura (O Estado Novo) que durava já há 40 anos, CAIU! Esta data, ficou também conhecida como “Revolução dos Cravos”.
Para alguns, que nasceram depois do 25 de Abril de 1974, esta Data é apenas um feriado. Pois sempre conheceram Portugal num regime democrático. Mas nem sempre foi assim

Astronomy picture of the day - 2016 April 24 - M16: Pillars of Star Creation
Image Credit: J. Hester, P. Scowen (ASU), HST, NASA
Explanation: Newborn stars are forming in the Eagle Nebula. This image, taken with the Hubble Space Telescope in 1995, shows evaporating gaseous globules (EGGs) emerging from pillars of molecular hydrogen gas and dust. Thegiant pillars are light years in length and are so dense that interior gas contracts gravitationally to form stars. At each pillars' end, the intense radiation of bright young stars causes low density material to boil away, leaving stellar nurseriesof dense EGGs exposed. The Eagle Nebula, associated with the open star cluster M16, lies about 7000 light years away. The pillars of creation were imaged again in 2007 by the orbiting Spitzer Space Telescope in infrared light, leading to the conjecture that the pillars may already have been destroyed by a local supernova, but light from that event has yet to reach the Earth.

Astronomy picture of the day - 2016 April 23 - Milky Way in Moonlight
Image Credit & Copyright: Babak Tafreshi (TWAN)
Explanation: A waning crescent moon, early morning twilight, and Al Hamra's city lights on the horizon can't hide the central Milky Way in this skyscape from planet Earth. Captured in a single exposure, the dreamlike scene looks southward across the region's grand canyon from Jabal Shams (Sun Mountain), near the highest peak in Oman, on the Arabian Peninsula. Mist, moonlight, and shadows still play along the steep canyon walls. Dark rifts along the luminous band of the Milky Way are the galaxy's cosmic dust clouds. Typically hundreds of light-years distant, they obscure starlight along the galactic plane, viewed edge-on from the Solar System's perspective.

Astronomy picture of the day - 2016 April 22 - NGC 7635: The Bubble Nebula
Image Credit: NASA, ESA, Hubble Heritage Team (STScI / AURA)
Explanation: Blown by the wind from a massive star, this interstellar apparition has a surprisingly familiar shape. Cataloged as NGC 7635, it is also known simply as The Bubble Nebula. Although it looks delicate, the 7 light-year diameter bubble offers evidence of violent processes at work. Above and left of the Bubble's center is a hot, O-type star, several hundred thousand times more luminous and around 45 times more massive than the Sun. A fierce stellar wind and intense radiation from that star has blasted out the structure of glowing gas against denser material in a surrounding molecular cloud. The intriguing Bubble Nebula and associated cloud complex lie a mere 7,100 light-years away toward the boastful constellation Cassiopeia. This sharp, tantalizing view of the cosmic bubble is a composite of Hubble Space Telescope image data from 2016, released to celebrate the 26th anniversary of Hubble's launch.
