China's Mars rover spotted on the surface by orbiting spacecraft - CNET

This before and after set of images shows the landing site of the Zhurong rover in Utopia Planitia on Mars. The rover is the smaller of the two dots in the upper right-hand corner.

The rover and lander can be seen as small specks near each other in the top right-hand side of the image. Zhurong is the lower of the two dots. The other notable spots are where parts of the landing system, including the parachute and heat shield, landed.

"The dark area surrounding the landing platform might be caused by the influence of the engine plume during landing," CNSA said in a statement. "The symmetrical bright stripes in the north-south direction of the landing platform might be from fine dust when the landing platform emptied the remaining fuel after landing."

NASA Space Station On-Orbit Status 7 June, 2021 - Unloading the Dragon Resupply Spacecraft -

The SpaceX Cargo Dragon resupply ship is open for business at the International Space Station following its automated docking early Saturday.

Now, the Expedition 65 crew turns its attention to a pair of U.S. spacewalks to upgrade the orbiting lab's power system.

Flight Engineer Megan McArthur and Commander Akihiko Hoshide worked throughout Monday unpacking and activating science experiments delivered Saturday aboard the SpaceX Cargo Dragon. The U.S. space freighter launched from Kennedy Space Center on Thursday carrying over 7,300 pounds of new science, supplies and solar arrays to replenish the orbiting lab.

Gargantua at Milky Way's Edge--"Star Eight Times Size of Sun Orbiting a Colossal Black

Home » Black Hole » Gargantua at Milky Way’s Edge–“Star Eight Times Size of Sun Orbiting a Colossal Black Hole”

“Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution,” said Liu Jifeng , astronomer at the National Astronomical Observatory of China and first author of a 2019 study of a black hole known as LB-1, discovered lurking at the far side of the Milky Way with a mass that is around 70 times larger than our sun with an orbiting blue monster, a star eight times the size of the sun..

Wind from supermassive black holes may help small galaxies thrive | New Scientist

Ignacio Martín-Navarro at the Institute of Astrophysics of the Canary Islands in Spain and his colleagues examined 124,163 satellite galaxies using data from the Sloan Digital Sky Survey. They analysed which of these galaxies were "quenched" – meaning that they were no longer forming stars – and aimed to figure out how such galaxies were affected by the supermassive black holes at the centre of their hosts.

Some central black holes called active galactic nuclei (AGNs) have vast outflows of energy perpendicular to the plane of their galaxies, and these winds are powerful enough to affect the nearby satellite galaxies.

Astronomers Discover Jets from Massive Protostars Might be Very Different from Lower-Mass Systems

Astronomers studying the fast-moving jet of material ejected by a still-forming, massive young star found a major difference between that jet and those ejected by less-massive young stars. The scientists made the discovery by using the U.S. National Science Foundation’s Karl G. Jansky Very Large Array (VLA) to make the most detailed image yet of the inner region of such a jet coming from a massive young star.

Spacecraft’s close-up of Jupiter’s mega moon is 1st in 20 years | WGN-TV

CAPE CANAVERAL, Fla. (AP) — NASA's Juno spacecraft has provided the first close-ups of Jupiter's largest moon in two decades.

Juno zoomed past icy Ganymede on Monday, passing within 645 miles (1,038 kilometers). The last time a spacecraft came that close was in 2000 when NASA's Galileo spacecraft swept past our solar system's biggest moon.

NASA released Juno's first two pictures Tuesday, highlighting Ganymede's craters and long, narrow features possibly related to tectonic faults. One shows the moon’s far side, opposite the sun.

Since the era of meteorological satellites began in the 1950s, continuous remote sensing instrument improvements have elevated Earth science and have significantly increased available atmospheric observations. Likewise, scientists have made considerable advancements in understanding Earth’s atmosphere, climate, and environment.

Pharrell Williams Wants Virginia Low-Income Families For His New Private School

Virginia native Pharrell Williams is doing his part to make sure low-income families are “happy” with their education goals. The musician/entrepreneur is launching a private school for those who can’t afford to send their children to a regular private school.

Williams is doing this through his non-profit initiative, Yellow, a 501(C)(3) non-profit established by the eclectic music producer to even the odds for all kids through education.

Connecting a star's chemical composition and planet formation | Penn Today

The most common technique for finding exoplanets , ones that exist outside of the solar system, involves the transit method, when an exoplanet moves between its star and the observer and causes a dip in the star's brightness. While most of the known exoplanets have been discovered using this method, this approach is limited because exoplanets can only be detected when their orbit and the observer are perfectly aligned and have short enough orbiting periods.

This raises the question, If planets can't be detected around a star, can their existence be inferred by studying the host star? The researchers found that the answer to this question is a qualified yes, with new methods helping astronomers better understand how the formation of exoplanets is related to the composition of the star they orbit.
