American scientists using NASA’s Chandra and Swift space observatories have captured a bright short-lived phenomenon – a sequence of concentric rings around a black hole, which are echoes from X-ray flares. Such images of giant X-ray rings provide new information about the dust contained in our Galaxy.
By the standards of the stars, the Sun is now “a moderately plump star in its prime.” But to thoroughly understand its evolution and try to predict future development, scientists need to find out what such bodies were like at earlier stages of development. Observations of young stars of the same type and, of course, modeling help a lot in this process.
The Perseverance rover successfully drilled its first hole in the Martian surface, but subsequent analysis showed that the sampling tube did not grab any of the intended Martian soil.
Juno’s onboard science instrument Juno Waves “listened” to radio emissions coming from the side of Jupiter’s magnetic field and gave scientists the opportunity to determine the boundaries of the regions with radiation.
Nearly three months after its first flight, the Ingenuity Mars Helicopter continues to make history on Mars in its extended mission. What began as a test program has now become a “tradition” that re-occurs once every two weeks.
