The Great Nebula in Orion, an immense, nearby starbirth region, is probably the most famous of all astronomical nebulas. Here, glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1500 light-years away. In the featured deep image in assigned colors highlighted by emission in oxygen and hydrogen, wisps and sheets of dust and gas are particularly evident. The Great Nebula in Orion can be found with the unaided eye near the easily identifiable belt of three stars in the popular constellation Orion. In addition to housing a bright open cluster of stars known as the Trapezium, the Orion Nebula contains many stellar nurseries. These nurseries contain much hydrogen gas, hot young stars, proplyds, and stellar jets spewing material at high speeds. Also known as M42, the Orion Nebula spans about 40 light years and is located in the same spiral arm of our Galaxy as the Sun.

Sándor Petőfi (1823 – 1849) was a Hungarian poet and liberal revolutionary. He is considered Hungary's national poet, and was one of the key figures of the Hungarian Revolution of 1848. He is the author of the poem “Talpra magyar” (“Rise, Hungarian”), written on the eve of the revolution, and is said to have inspired the the war of independence revolution in the Kingdom of Hungary that grew into a war for independence from the Austrian Empire. The Poem's words became its National Song (Nemzeti dal). It is believed that he died in the Battle of Segesvár, one of the last battles of the war.

NASA Astronomy Picture of the Day:

What's that black spot on Jupiter? No one is sure. During one pass of NASA's Juno over Jupiter, the robotic spacecraft imaged an usually dark cloud feature informally dubbed the Abyss. Surrounding cloud patterns show the Abyss to be at the center of a vortex. Since dark features on Jupiter's atmosphere tend to run deeper than light features, the Abyss may really be the deep hole that it appears -- but without more evidence that remains conjecture. The Abyss is surrounded by a complex of meandering clouds and other swirling storm systems, some of which are topped by light colored, high-altitude clouds. The featured image was captured in 2019 while Juno passed only about 15,000 kilometers above Jupiter's cloud tops. The next close pass of Juno near Jupiter will be in about three weeks.

It has been reported that 11,000 Political Groups have spent $14.7 Billion to Influence the 2024 U.S. Election. What can we do? ...We can allow to be persuaded by all the disinformation, or we can let our conscience be our guide and vote for the candidate who we would be proud to invite into our homes, talk to our family and inspire our children or grandchildren. Anything else is a compromise we cannot afford.

Saturn is bright in Earth's night skies. Telescopic views of the outer gas giant planet and its beautiful rings often make it a star at star parties. But this stunning view of Saturn's rings and night side just isn't possible from telescopes in the vicinity of planet Earth. Peering out from the inner Solar System they can only bring Saturn's day side into view. In fact, this image of Saturn's slender sunlit crescent with night's shadow cast across its broad and complex ring system was captured by the Cassini spacecraft. A robot spacecraft from planet Earth, Cassini called Saturn orbit home for 13 years before it was directed to dive into the atmosphere of the gas giant on September 15, 2017. This magnificent mosaic is composed of frames recorded by Cassini's wide-angle camera only two days before its grand final plunge. Saturn's night will not be seen again until another spaceship from Earth calls.

"On 29 October 1969, two scientists established a connection between computers some 350 miles away and started typing a message. Halfway through, it crashed. They sat down with the BBC 55 years later"......"I was on the phone with Bill when we tried this. I told him I typed the letter L. He told me he had received the letter L and echoed it back. I told him that it printed. Then I typed the letter O. Again, it worked fine. I typed the letter G. Bill told me his system had crashed, and he would call me back"..... Read more at The BBC ➜

NASA Astronomy Picture of the Day:

Big, beautiful spiral galaxy NGC 6744 is nearly 175,000 light-years across, larger than our own Milky Way. It lies some 30 million light-years distant in the southern constellation Pavo but appears as only a faint smudge in the eyepiece of a small telescope. We see the disk of the nearby island universe tilted towards our line of sight in this remarkably deep and detailed galaxy portrait, a telescopic image that spans an area about the angular size of a full moon. In it, the giant galaxy's elongated yellowish core is dominated by the light from old, cool stars. Beyond the core, grand spiral arms are filled with young blue star clusters and speckled with pinkish star forming regions. An extended arm sweeps past smaller satellite galaxy NGC 6744A at the upper left. NGC 6744's galactic companion is reminiscent of the Milky Way's satellite galaxy the Large Magellanic Cloud.
