Let History Never Forget The Name Enterprise

A cidade de Parintins está nos dias de festa religiosa, e então, resolvi relembrar a visita no local mais alto da torre da catedral, onde está localizado a estátua de Nossa Senhora do Carmo. #TorredaCatedraldeParintins Data de registro: 16 de julho de 2018 às 18h18

Travel Posters of Fantastic Excursions

What would the future look like if people were regularly visiting to other planets and moons? These travel posters give a glimpse into that imaginative future. Take a look and choose your destination:

The Grand Tour

Our Voyager mission took advantage of a once-every-175-year alignment of the outer planets for a grand tour of the solar system. The twin spacecraft revealed details about Jupiter, Saturn, Uranus and Neptune – using each planet’s gravity to send them on to the next destination.

Mars

Our Mars Exploration Program seeks to understand whether Mars was, is, or can be a habitable world. This poster imagines a future day when we have achieved our vision of human exploration of the Red Planet and takes a nostalgic look back at the great imagined milestones of Mars exploration that will someday be celebrated as “historic sites.”

Earth

There’s no place like home. Warm, wet and with an atmosphere that’s just right, Earth is the only place we know of with life – and lots of it. Our Earth science missions monitor our home planet and how it’s changing so it can continue to provide a safe haven as we reach deeper into the cosmos.

Venus

The rare science opportunity of planetary transits has long inspired bold voyages to exotic vantage points – journeys such as James Cook’s trek to the South Pacific to watch Venus and Mercury cross the face of the sun in 1769. Spacecraft now allow us the luxury to study these cosmic crossings at times of our choosing from unique locales across our solar system.

Ceres

Ceres is the closest dwarf planet to the sun. It is the largest object in the main asteroid belt between Mars and Jupiter, with an equatorial diameter of about 965 kilometers. After being studied with telescopes for more than two centuries, Ceres became the first dwarf planet to be explored by a spacecraft, when our Dawn probe arrived in orbit in March 2015. Dawn’s ongoing detailed observations are revealing intriguing insights into the nature of this mysterious world of ice and rock.

Jupiter

The Jovian cloudscape boasts the most spectacular light show in the solar system, with northern and southern lights to dazzle even the most jaded space traveler. Jupiter’s auroras are hundreds of times more powerful than Earth’s, and they form a glowing ring around each pole that’s bigger than our home planet. 

Enceladus

The discovery of Enceladus’ icy jets and their role in creating Saturn’s E-ring is one of the top findings of the Cassini mission to Saturn. Further Cassini discoveries revealed strong evidence of a global ocean and the first signs of potential hydrothermal activity beyond Earth – making this tiny Saturnian moon one of the leading locations in the search for possible life beyond Earth.

Titan

Frigid and alien, yet similar to our own planet billions of years ago, Saturn’s largest moon, Titan has a thick atmosphere, organic-rich chemistry and surface shaped by rivers and lakes of liquid ethane and methane. Our Cassini orbiter was designed to peer through Titan’s perpetual haze and unravel the mysteries of this planet-like moon.

Europa

Astonishing geology and the potential to host the conditions for simple life making Jupiter’s moon Europa a fascinating destination for future exploration. Beneath its icy surface, Europa is believed to conceal a global ocean of salty liquid water twice the volume of Earth’s oceans. Tugging and flexing from Jupiter’s gravity generates enough heat to keep the ocean from freezing.

This photograph of Neptune was reconstructed from two images taken by Voyager 2’s narrow-angle camera, through the green and clear filters. At the north (top) is the Great Dark Spot, accompanied by bright, white clouds that undergo rapid changes in appearance.

This is not just an incredible view of Earth, it’s also a fantastic illustration of the terminator. (No not that one!) The terminator is the moving line that separates the day side from the dark night side of a planetary body. From this vantage point you can make out the gradual transition to darkness that is experienced as twilight on the surface. This image was captured on Aug. 31 by astronaut Jeff Williams (@Astro_Jeff) while on board the ISS.

What’s Up - January 2018

What’s Up For January? 

Quadrantid meteors, a West Coast-favoring total lunar eclipse and time to start watching Mars!

This month the new year’s first meteor shower fizzles, Mars meets Jupiter in the morning sky and the U.S. will enjoy a total lunar eclipse!

Most meteor showers radiate from recognizable constellations. Like the Leonids, Geminids and Orionids.

But the Quadrantids are meteors that appear to radiate from the location of the former Quadrans Muralis constellation, an area that’s now part of the constellation Bootes.

The Quadrantids’ peak lasts for just a few hours, and sadly, this year their timing coincides with a very bright, nearly full moon that will wash out most of the meteors.

You can look in any direction to see all the meteor showers. When you see one of these meteors, hold a shoestring along the path it followed. The shoestring will lead you back to the constellation containing the meteor’s origin.

On the morning of January 6th, look in the south-southeast sky 45 minutes before sunrise to see Jupiter and fainter Mars almost as close as last month’s Jupiter and Venus close pairing.

Mars is only one-sixth the apparent diameter of Jupiter, but the two offer a great binocular and telescopic view with a pretty color contrast. They remain in each other’s neighborhood from January 5th through the 8th.

Finally, to end the month, a great total lunar eclipse favors the western U.S., Alaska, and Hawaii and British Columbia on January 31st. Australia and the Pacific Ocean are well placed to see a major portion of the eclipse–if not all of it.

Falta 1 mês pra sonda Juno chegar em Júpiter. Comecei uma série no canal para explicar a missão. O primeiro vídeo já está no ar - https://youtu.be/qjxJ12IB4MQ

Essa imagem capturada pela Wide Field Camera 3, a WFC3 do Hubble, mostra a galáxia chamada UGC 6093. Como se pode ver facilmente, a UGC 6093 é conhecida como uma galáxia espiral barrada - ela tem belos braços que espiralam a partir de uma barra que corta o centro da galáxia. Ela é classificada como uma galáxia ativa, o que significa que ela abriga um núcleo ativo de galáxia, ou um AGN, uma região compacta no centro da galáxia onde o material está centro dragado em direção do buraco negro supermassivo central. À medida que esse buraco negro devora material, ele emite intensa radiação, fazendo com que a galáxia brilhe intensamente. Mas a UGC 6093 é mais exótica ainda. A galáxia age essencialmente como um gigantesco laser astronômico que espalha sua luz nas microondas, não na luz visível, esse tipo de objeto é chamada de megamaser, sendo maser o termo usado para um laser de microondas. Os megamasers como a UGC 6093, podem ser cerca de 100 milhões de vezes mais brilhantes do que os masers encontrados em galáxias como a Via Láctea. A WFC3 do Hubble, observa a luz sendo espalhada em uma grande variedade de comprimentos de ondas, desde o infravermelho próximo, passando pela parte visível, até o ultravioleta próximo. Ela tem dois canais que detectam e processam os tipos diferentes de luz, permitindo que os astrônomos estudem uma grande quantidade de fenômenos astrofísicos, por exemplo, o canal UV-visível pode estudar galáxias que estão passando pelo processo de formação de estrelas, enquanto que o canal do infravermelho próximo pode estudar a luz desviada para o vermelho de galáxias no universo distante. Essas imagens multi-espectrais feitas pelo Hubble são de suma importância para estudar as galáxias megamasers.
