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

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.

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.

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.

Explanation: Can one galaxy hide behind another? Not in the case of SDP.81. Here the foreground galaxy, shown in blue in an image taken by the Hubble Space Telescope, acts like a huge gravitational lens, pulling light from a background galaxy, shown in red in an image taken in radio waves by the Atacama Large Millimeter Array (ALMA), around it, keeping it visible. The alignment is so precise that the distant galaxy is distorted into part of a ring around the foreground galaxy, a formation known as an Einstein ring. Detailed analysis of the gravitational lens distortions indicate that a small dark satellite galaxy participates in the deflections, bolstering indication that many satellite galaxies are quite dim and dominated by dark matter. That small galaxy is depicted by a small white dot on the left. Although spanning only a few arcseconds, the featured Einstein ring is really tens of thousands of light years across.

Angola: 12 mortos e 4 desaparecidos em Luanda devido ao mau tempo

Pelo menos 12 pessoas morreram e quatro em estão desaparecidas Luanda, Angola, devido ao desabamento de casas e aluimento de terras após as chuvas intensas. O balanço provisório é dos serviços de Proteção Civil e Bombeiros, avança aRádio Nacional de Angola.

A chuva continua a cair com grande intensidade, sobretudo no norte do país.

Ainda segundo a rádio, os municípios de Viana, Cacuaco, Ingombotas e Sambizanga foram os mais afectados na capital angolana.

Só em Cacuaco registaram-se nove mortos e pelo menos três pessoas estão desaparecidas.

As autoridades dão conta de um cenário de caos nas últimas 24 horas, com muitas inundações e centenas de casas alagadas em Angola e reforçam o apelo para que os habitantes das zonas de risco peçam acomodação em zonas de maior segurança.
