Story summary

Astronomers discovered ASKAP J1832-0911, a cosmic object emitting radio waves and X-rays every 44 minutes, 14,700 light-years away.
This finding may indicate a new class of long-period radio transients, challenging current astrophysical models.
Scientists are investigating theories, including magnetar or white dwarf binary origins.
The search for similar signals continues with advanced telescopes, including the James Webb Space Telescope.
Microbial life signs were detected on exoplanet K2-18b, located 124 light-years from Earth.
