Explanation: The star closest to the Sun has a planet similar to the Earth. As announced yesterday, recent observations confirmed that this planet not only exists but inhabits a zone where its surface temperature could allow liquidwater, a key ingredient for life on Earth. It is not yet known if this planet, Proxima b, has any life. Even if not, its potential ability to sustain liquid water might make it a good first hop for humanity's future trips out into the Milky Way Galaxy. Although the planet's parent star, Proxima Centauri, is cooler and redder than our Sun, one of the other two stars in the Alpha Centauri star system is very similar to our Sun. The featured image shows the sky location of Proxima Centauri in southern skies behind the telescope that made many of the discovery observations: ESO's 3.6-meter telescope in La Silla, Chile. The discovered planet orbits close in -- so close one year there takes only 11 days on Earth. The planet was discovered by the ESO's Pale Red Dot collaboration. Although seemingly unlikely, if Proxima b does have intelligent life, at 4.25 light years distance it is close enough to Earth for two-way communication.

Sismo em Itália faz dezenas de mortos


Quatro mil portugueses nas zonas afetadas pelo sismo

Pelo menos 38 pessoas morreram na sequência de um forte sismo de 6.0 na escala de Richter, em Itália, segundo o último balanço da Proteção Civil italiana. O número de vítimas pode vir a aumentar, visto que há indicação de vários feridos e de famílias inteiras soterradas.

"Neste momento, há 38 vítimas confirmadas", afirmou o porta-voz do escritório de emergência da Proteção Civil, Immacolata Postiglione, em conferência de imprensa em Roma. Sobre o número de desaparecidos, Postiglione recusou precisar um número.

Explanation: What are these unusual lumps on Mars? As NASA's robotic Curiosity rover continues rolling across Mars, it is now approaching Murray Buttes. Several of the 15-meter high buttes are visible ahead in this horizontally compressed 360-degree across image taken inside Gale Crater earlier this month. The buttes are thought similar to Earth buttes in that they are capped with dense rock that is relatively resistant to erosion. In the image center isCuriosity's "arm" and "hand" used to examine rocks up close, drill into rocks, and collect samples. Curiosity has reached its four year anniversary on Mars and has been cleared to spend the next two years further exploring the slopes ofMount Sharp, the peak of which is the distant light-colored structure visible on the far left.

Astronomy picture of the day - 2016 August 23 - Gigantic Jet Lightning over China

Explanation: That's no meteor. While watching and photographing this year's Perseid Meteor Shower, something unexpected happened: a gigantic jet erupted from a nearby cloud. The whole thing was over in a flash -- it lasted less than a second -- but was fortunately captured by an already-recording digital camera. Gigantic jets are a rare form of lightning recognized formally only a few years ago. The featured high resolution color image, taken near the peak ofShikengkong mountain in China, may be the best image yet of this unusual phenomena. The same event appears to have been captured simultaneously by another photographer, further away. The gigantic jet appears to start somewhere in a nearby thundercloud and extend upwards towards Earth's ionosphere. The nature of gigantic jets and their possible association with other types of Transient Luminous Events (TLEs) such as blue jets and red sprites remains an active topic of research.

A anedota "alantjana" do dia - O "xécapi"

O Ti Zé Chaparro, aproveitando a viagem a Mértola, foi ao médico fazer um 'xécápi'.

Pergunta o médico.
- Sr. José, o senhor está em muito boa forma para 40 anos.
- E eu disse que tinha 40 anos?
- Quantos anos o senhor tem?
- Fiz 57 em agora em Março.
- Não me diga! E quantos anos tinha o seu pai quando morreu?
- E eu disse que meu pai morreu?
- Oh, desculpe! Quantos anos tem o seu pai?
- O velho tem 81.
- 81? Que bom! E quantos anos tinha o seu avô quando morreu?
- E eu disse que ele morreu?
- Sinto muito. E quantos anos ele tem?
- 103, e ainda anda de bicicleta.
- Fico feliz em saber. E o seu bisavô? Morreu de quê?
- E eu disse que ele tinha morrido? Ele está com 124 e vai casar na
semana que vem.
- Agora já é demais! - Diz o médico revoltado.
- Por que é que um homem de 124 anos iria querer casar?
- E eu disse que ele QUERIA se casar? Não queria nada, mas engravidou a moça!..

Explanation: If you went outside at exactly the same time every day and took a picture that included the Sun, how would the Sun's position change? With great planning and effort, such a series of images can be taken. The figure-8 path the Sun follows over the course of a year is called an analemma. At the Winter Solstice in Earth's northern hemisphere, the Sun appears at the bottom of the analemma. Analemmas created from different latitudes appear at least slightly different, as well as analemmas created at a different time each day. With even greater planning and effort, the series can include a total eclipse of the Sun as one of the images. Pictured is such a total solar eclipse analemma or Tutulemma - a term coined by the photographers based on the Turkish word for eclipse. The featured composite image sequence was recorded from Turkey starting in 2005. The base image for the sequence is from the total phase of a solar eclipse as viewed from Side, Turkey on 2006 March 29. Venus was also visible during totality, toward the lower right. If you want to create your own USA-based tutulemma ending at next August's total solar eclipse, now would be good time to start.

Brasil campeão olimpico de futebol



Neymar não tremeu na marcação da grande penalidade decisiva e deu a medalha de ouro ao Brasil.

O Brasil tornou-se no novo campeão olímpico de futebol, depois de bater a Alemanha nas grandes penalidades, por 5-4, após o empate a uma bola registado nos 120 minutos de jogo corrido.

Neymar foi o herói do encontro, ao marcar, logo aos 27 minutos, de livre direto, um golo maravilhoso que colocou os brasileiros em vantagem. No entanto, aos 59, Max Meyer fez o empate que iria subsistir até ao final dos 120 minutos.

Nos penáltis, Nils Petersen falhou o quinto penálti para a Alemanha, sendo que todos os jogadores canarinhos chamados a bater converteram. Neymar, encarregue da marcação da última grande penalidade, não deu hipótese de defesa a Timo Horn.
