Explanation: Massive star IRS 4 is beginning to spread its wings. Born only about 100,000 years ago, material streaming out from this newborn star has formed the nebula dubbed Sharpless 2-106 Nebula (S106), featured here. A large disk of dust and gas orbiting Infrared Source 4 (IRS 4), visible in brown near the image center, gives the nebula an hourglass or butterfly shape. S106 gas near IRS 4 acts as an emission nebula as it emits light after being ionized, while dust far from IRS 4 reflects light from the central star and so acts as a reflection nebula. Detailed inspection of a relevant infrared image of S106 reveal hundreds of low-mass brown dwarf stars lurking in the nebula’s gas. S106 spans about 2 light-years and lies about 2000 light-years away toward the constellation of the Swan (Cygnus).

Milky Way over Pyramid of the Feathered Serpent : To see the feathered serpent descend the Mayan pyramid requires exquisite timing. You must visit El Castillo – in Mexico’s Yucatán Peninsula – near an equinox. Then, during the late afternoon if the sky is clear, the pyramid’s own shadows create triangles that merge into the famous illusion of the slithering viper. Also known as the Temple of Kukulkan, the impressive step-pyramid stands 30 meters tall and 55 meters wide at the base. Built up as a series of square terraces by the pre-Columbian civilization between the 9th and 12th century, the structure can be used as a calendar and is noted for astronomical alignments. To see the central band of our Milky Way Galaxy descend overhead the Mayan pyramid, however, requires less exquisite timing. Even the ancient Mayans might have been impressed, though, to know that the exact positions of the Milky Way, Saturn (left) and Jupiter (right) in the featured image give it a time stamp more specific than equinox – in fact 2019 April 7 at 5 am. via NASA

A Venus Flyby via NASA https://ift.tt/3sv3XhX

On a mission to explore the inner heliosphere and solar corona, on July 11, 2020 the Wide-field Imager on board NASA’s Parker Solar Probe captured this stunning view of the nightside of Venus at distance of about 12,400 kilometers (7,693 miles). The spacecraft was making the third of seven gravity-assist flybys of the inner planet. The gravity-asssist flybys are designed to use the approach to Venus to help the probe alter its orbit to ultimately come within 6 million kilometers (4 million miles) of the solar surface in late 2025. A surprising image, the side-looking camera seems to peer through the clouds to show a dark feature near the center known as Aphrodite Terra, the largest highland region on the Venusian surface. The bright rim at the edge of the planet is nightglow likely emitted by excited oxygen atoms recombining into molecules in the upper reaches of the atmosphere. Bright streaks and blemishes throughout the image are likely due to energetic charged particles, and dust near the camera reflecting sunlight. Skygazers from planet Earth probably recognize the familiar stars of Orion’s belt and sword at lower right.

“Using nothing more than Newton’s laws of gravitation, we astronomers can confidently predict that several billion years from now, our home galaxy, the Milky Way, will merge with our neighboring galaxy Andromeda. Because the distances between the stars are so great compared to their sizes, few if any stars in either galaxy will actually collide.

Any life on the worlds of that far-off future should be safe, but they would be treated to an amazing, billion-year-long light show a dance of a half a trillion stars to music first heard on one little world by a man who had but one true friend.”

(via Voyager 2 is gathering science data again after recovering from a glitch in interstellar space | Space)

All five remaining instruments on NASA’s venerable Voyager 2 spacecraft are back to gathering science data after power overuse in late January interrupted the probe’s operations.

NASA made the announcement yesterday (March 3), over a month after the incident occurred. Troubleshooting for the spacecraft is a slow process because of its distance from Earth; it takes 17 hours for each command to reach the probe and for data indicating its efficacy to reach engineers.

Hello!! Its wonderful to be able to ask questions, thank you!

About Perseverance, does it have a self-repair option? And as Curiosity is still operational, will they run missions together? Or will they split up to cover more distance?

Is this a sign that we're close to being able to set foot on Mars?

My final question is how do you receive the messages from such a long distance?

Thanks for all your hard work! 加油/Good luck!

“Is this a sign that we are close to being able to set foot on Mars?”

Will the robot be able to send vedio footage?
