Reality, meet headlines. Her documented “work” on the project is janitorial! MIT news article on the image and the team: http://news.mit.edu/2019/mit-haystack-first-image-black-hole-0410 From the article: An international team of over 200 astronomers, including scientists from MIT’s Haystack Observatory, has captured the first direct images of a black hole. They accomplished this remarkable feat by coordinating the power of eight major radio observatories on four continents, to work together as a virtual, Earth-sized telescope. In a series of papers published today in a special issue of Astrophysical Journal Letters, the team has revealed four images of the supermassive black hole at the heart of Messier 87, or M87, a galaxy within the Virgo galaxy cluster, 55 million light years from Earth. … The Haystack EHT team includes John Barrett, Roger Cappallo, Joseph Crowley, Mark Derome, Kevin Dudevoir, Michael Hecht, Lynn Matthews, Kotaro Moriyama, Michael Poirier, Alan Rogers, Chester Ruszczyk, Jason SooHoo, Don Sousa, Michael Titus, and Alan Whitney. Additional contributors were MIT alumni Daniel Palumbo, Katie Bouman, Lindy Blackburn, Sera Markoff, and Bill Freeman, a professor in MIT’s Department of Electrical Engineering and Computer Science. She’s listed as an “additional contributor.”  Topkek. reblogging because ive seen katie boumans name several times but this is the first time ive heard about andrew chael. he deserves to be recognized. 850k lines of code is no joke.

Anaconda, Waves, and Holes: The collision of a pair of neutron stars, marked by ripples through the fabric of space-time and a flaslh brighter than a billion suns, has been witnessed for the first time in the most intensely observed astronomical event to date. The sequence, in which the two ultra-dense stars spiralled inwards, violently collided and, in all likelihood, immediately collapsed into a black hole, was first picked up by the US-based Laser Interferometer Gravitational-Wave Observatory (Ligo). It's probably the first observation of a black hole being created where there was none before. Gravitational waves were first directly detected two years ago, proving Albert Einstein's theory of general relativity. Those gravitational waves were the result of two black holes colliding, and the signal lasted for only a fraction of a second. Because black holes don't emit light, these waves were invisible and only "heard" as thumps This discovery of two neutron stars colliding to create the same type of waves, in addition to light, allowed astronomers to study gravitational waves in a new way. The signal lasted for 100 seconds, providing them with even more data and insight. It revealed that light and gravitational waves travel at the same speed. Previously, scientists had speculated that the sheer force of neutron star collisions would be enough to force extra neutrons into the nuclei of atoms, forging heavy elements like gold and platinum, but until now this idea was purely theoretical. "This is the first real confirmation that heavy elements such as gold, platinum and uranium are either solely or predominantly produced in binary neutron star collisions," Dave Reitze, executive director of Ligo, "The wedding band on your finger or the gold watch you're wearing was most likely produced a billion years ago by two neutron stars colliding. That's pretty cool. Theories and mysteries were tested and revealed in this rare observation. Events like this happen less than 100 times per million years in a galaxy First-Seen Neutron Stars Collision Solve Major Astronomical Mysteries

Anaconda, Memes, and New York: DARK SIDE Ancaman Bencana ika Suhu Bumi Naik 1,5 erajat Celsius Temperatur permukaan bumi memang bervariasi. Ada yang luar biasa panas seperti Sahara hingga yang luar biasa dingin seperti Antartika Peter deMenocal, seorang ilmuwan iklim purba di Lamont-Doherty Earth Observatory, Columbia University, New York, berkata bahwa kenaikan temperatur rata-rata planet bumi adalah permasalahan besar, walaupun hanya beberapa derajat saja 1. Makanan Perubahan iklim mempengaruhi ekosistem dan makanan. Lautan yang menyediakan 20 persen makanan manusia, misalnya, menjadi lebih asam akibat peningkatan karbon dioksida yang terserap. Hal ini membuat ribuan spesies seperti tiram, kepiting, dan terumbu kesulitan untuk membuat cangkang pelindungnya. Sementara itu, kenaikan dua derajat celcius pada daratan dapat melipatgandakan kekeringan air dan menurunkan hasil panen para petani.Temperatur yang terlalu panas juga dapat menghambat pertumbuhan tanaman yang berbunga seperti jagung dan biji-bijian lainnya 2. Tempat tinggal Sebanyak 40 persen populasi dunia hidup dalam jarak 100 kilometer dari laut. Dengan meningkatnya temperatur dunia, permukaan air laut yang naik akibat es yang meleleh dapat menghancurkan kota dan tempat tinggal mereka 3. Energi Menurut Departemen Energi Amerika Serikat, sebanyak tujuh persen dari listrik di negara adidaya ini dibangkitkan menggunakan tenaga air. Akan tetapi, perubahan pola hujan dapat mengurangi kekuatan tenaga air 4. Kesehatan Peningkatan temperatur dan perubahan pola hujan telah dihubungkan dengan penyebaran penyakit yang ditularkan melalui vektor seperti penyakit Lyme dan malaria. Selain itu, beberapa area seperti Timur Tengah dan Amerika Barat bisa menjadi tidak dapat ditinggali manusia karena temperatur yang ekstrem. Sebab, temperatur yang tinggi biasanya juga dibarengi oleh tingkat kelembapan yang tinggi. Kedua hal tersebut membuat keringat tidak bisa menguap dan mendinginkan tubuh manusia. Kondisi ini dapat berujung pada kematian Bencana ini diperkirakan akan terjadi dalam 15 tahun, antara 2032 dan 2039 ketika temperatur bumi naik sebanyak 1,5 derajat celcius Sumber: http:-nationalgeographic.co.id
