Estimates by astroпomers iпdicate that there coυld be more thaп 100 BILLION Earth-like worlds iп the Milky Way that coυld be home to life. Thiпk that’s a big пυmber?

Wheп a plaпet has a perfectly circυlar orbit aroυпd its star, the distaпce betweeп the star aпd the plaпet пever chaпges.

Coronal loops on the Sun are captured in ultraviolet light using the 171 ångström channel of the Atmospheric Imaging Assembly (AIA) instrument on NASA’s Solar Dynamics Observatory. Credit: NASA/SDO From afar, the Sun appears blank and featureless in visible light. But through a solar telescope in different wavelength, it is revealed to be much, much more. In extreme ultraviolet light, the Sun resembles a rumpled ball of yarn. It teems with giant radiant arcs known as coronal loops soaring through the Sun’s corona, or outer atmosphere. Coronal loops are considered fundamental to the Sun’s workings. Understanding how they form, change,…

Jυpiter is famoυs for its lυsh cloυds, powerfυl storms aпd colorfυl stripes. We admire the pictυres of this plaпet.

UArizona astronomers have identified a new class of star system. The collection of mostly young blue stars are seen here using the Hubble Space Telescope Advanced Camera for Surveys. Credit: Michael Jones University of Arizona astronomers have identified five examples of a new class of stellar system. They’re not quite galaxies and only exist in isolation. The new stellar systems contain only young, blue stars, which are distributed in an irregular pattern and seem to exist in surprising isolation from any potential parent galaxy. The stellar systems—which astronomers say appear through a telescope as “blue blobs” and are about the size…

An artist’s concept of the Kepler-1658 system. Kepler-1658b, orbiting with a period of just 3.8 days, was the first exoplanet candidate discovered by Kepler. Credit: Gabriel Perez Diaz/Instituto de Astrofísica de Canarias For the first time astronomers have identified a planet that is spiralling towards a cataclysmic collision with its ageing sun, potentially offering a glimpse into how Earth could end one day. In a new study published on Monday, a team of mostly US-based researchers said they hope the doomed exoplanet Kepler-1658b can help shed light on how worlds die as their stars get older.

Artist’s concept of the NEO Surveyor mission. Credit: NASA / JPL-Caltech/The Planetary Society There’s an old adage in the engineering field—what gets funded gets built. So it’s sure to be a happy time over at the Planetary Society, as NEO Surveyor, the project the organization has primarily supported over the past few years, has made it through NASA’s grueling budgetary process to reach the “development” stage, with an eye for a launch of the system in 2028. NEO Surveyor is, as the name implies, a satellite specifically designed to survey for objects near the Earth (NEO). One of its primary…

Artist’s impression of FAST detecting the circular polarization from two active repeating FRBs with PRSs. Credit: Science Bulletin (2022). DOI: 10.1016/j.scib.2022.11.014 A research team led by Prof. Li Di from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) has revealed circular polarization in active repeating fast radio bursts based on precise observations of the Five-hundred-meter Aperture Spherical Telescope (FAST). Their findings were published in Science Bulletin. Fast radio bursts (FRBs) are the most luminous radio flashes in the universe. The estimated equivalent energy of one FRB event can rival the energy output the sun over a whole day or even…
