@AcreditaNisso? A Nasa anunciou hoje que encontrou o primeiro sistema solar com sete planetas de tamanho similar ao da Terra pela primeira vez na história. O sistema foi encontrado a cerca de 39 anos-luz de distância–uma distância relativamente pequena em termos cósmicos. Dos sete planetas, três estão dentro de uma zona habitável, onde é possível ter água líquida e, consequentemente, vida. Tudo começou em 2016, quando Michael Gillon, astrônomo na Universidade de Liège, na Bélgica, descobriu três exoplanetas orbitando uma estrela anã. Ele e seu grupo encontraram os astros após notar que a Trappist-1 escurecia periodicamente, indicando que um planeta poderia estar passando na frente da estrela e bloqueando a luz. Para estudar a descoberta mais a fundo, o pesquisador usou telescópios localizados na Terra, como o Star, da Universidade de Liège, o telescópio de Liverpool, na Inglaterra, e o Very Large Telescope da ESO, no Chile. Já no espaço, Gillon usou o Spitzer, o telescópio espacial da Nasa, durante 20 dias. Com as observações no solo e no espaço, os cientistas calcularam que não havia apenas três exoplanetas, mas sete. A partir dessa análise, foi possível descobrir o tempo de translação, a distância da estrela, a massa e o diâmetro dos sete astros. De acordo com os pesquisadores, ainda é preciso observar o sistema solar por mais algum tempo para saber novos detalhes, como a existência de água líquida. Fonte: Exame .

Kupu-kupu kosmik yang ditunjukkan dalam gambar Hubble Space Telescope ini memilki banyak nama. Selain sering disebut Twin Jet Nebula juga memiliki nama lain yang sedikit kurang puitis: PN M2-9. Huruf M di nama ini mengacu pada Rudolph Minkowski, seorang astronom Jerman-Amerika yang menemukan nebula di tahun 1947. Sedangkan PN, mengacu pada fakta bahwa M2-9 adalah nebula planet (Planetary Nebula). Bercahaya dan memperluas cangkang gas yang jelas terlihat dalam gambar. Ini merupakan tahap akhir dari hidup sebuah bintang tua bermassa menengah. Bintang tidak hanya melontarkan lapisan luarnya, tapi inti yang tersisa kini menerangi lapisan ini menghasilkan pertunjukan cahaya spektakuler seperti yang terlihat di sini. Meskipun penampilannya indah, awan kosmik ini mengandung jet material bintang, yang dilontarkan ke luar angkasa dengan kecepatan lebih dari 1 juta km-jam Gambar sebelumnya dari Twin Jet Nebula menggunakan data yang dikumpulkan oleh Hubble, Wide Field Planetary Camera 2 dirilis pada tahun 1997.

10 JAN: Astronomers have discovered what happens when the eruption from a supermassive black hole is swept up by the collision and merger of two galaxy clusters. This composite image contains X-rays from Chandra (blue), radio emission from the GMRT (red), and optical data from Subaru (red, green, and blue) of the colliding galaxy clusters called Abell 3411 and Abell 3412. These and other telescopes were used to analyse how the combination of these two powerful phenomena can create an extraordinary cosmic particle accelerator.

KIC 8462852, otherwise known as Tabby’s star, is a real weirdo, celestially speaking. Over the last century, the star dimmed by 14 percent for no apparent reason, which led people to believe that it was surrounded by some sort of megastructure...because aliens. Obviously that’s not the case, but in the last four years, researchers watched a severe drop off in its brightness. Josh Simon and Ben Montet, researchers from Caltech, have been scratching their heads at data from NASA’s Kepler space telescope. “This star was already completely unique because of its sporadic dimming episodes. But now we see that it has other features that are just as strange, both slowly dimming for almost three years and then suddenly getting fainter much more rapidly,” said Simon. Montet continued, “It’s a big challenge to come up with a good explanation for a star doing three different things that have never been seen before. But these observations will provide an important clue to solving the mystery of KIC 8462852.” We can’t wait to see what this star’s deal is!

Forget fireworks this New Year's Eve and get your binoculars ready to see the C-2016 U1 NEOWISE comet. NASA has announced that the comet zooming through the inner Solar System *could* be so bright over the next week that you can see it with binoculars and maybe even with the naked eye between now and January 14. Although the prospect of being able to see a comet zoom past might sound scary, don't worry, comet C-2016 U1 NEOWISE has already made it through the closest pass of Earth on December 13, at a distance of around 106 million km (66 million miles). Pictured above is the comet taken with a telescope on Dec. 23 in Austria by Michael Jäger. (You can expect the comet to look a little like this, except slightly further away.) The best place to view the comet is from the Northern Hemisphere, and you should look towards the southeastern sky right before dawn. Never forget to look up!

Repost @nasa ・・・ Globular clusters offer some of the most spectacular sights in the night sky. These ornate spheres contain hundreds of thousands of stars, and reside in the outskirts of galaxies. The Milky Way contains over 150 such clusters - and the one shown in this Hubble Space Telescope image is one of the more unusual ones. It is younger than expected. Although most globular clusters are much older than the majority of stars in their host galaxy, NGC 362 bucks the trend, with an age lying between 10 and 11 billion years old. For reference, the age of the Milky Way is estimated to be above 13 billion years.

Phew! In the early ‘90s, the Hubble Space Telescope was used to analyze type Ia supernovae, a.k.a. the thermonuclear explosion of dying stars, which led to a theory that dark energy is the cause of the accelerated expansion of the universe. Now, a team of scientists from Oxford University’s Department of Physics are analyzing ten times the original data and have found the theory wanting. “The evidence for accelerated expansion is, at most, what physicists call ‘3 sigma.’ This is far short of the ‘5 sigma’ standard required to claim a discovery of fundamental significance,” said Professor Subir Sarkar, a fellow at the Neils Bohr Institute and the leader of this study.
