Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full Moon. What backyard observers don't see is a swarm of nearly three dozen small satellite galaxies circling the Andromeda galaxy, like bees around a hive ..read more

Researchers have found that stars in the early universe may have formed from 'fluffy' molecular clouds. Using the ALMA telescope to observe the Small Magellanic Cloud -- whose environment is similar to the early universe -- they observed that about 60% of the observed clouds had the common filamentary structure, while the remaining 40% had a 'fluffy' shape. These results could provide new insights into the formation of stars in the universe ..read more

Within the Dark Energy Spectroscopic Instrument's early data, scientists have uncovered the largest samples ever of intermediate-mass black holes and dwarf galaxies hosting an active black hole, more than tripling the existing census of both. These large statistical samples will allow for more in-depth studies of the dynamics between dwarf galaxy evolution and black hole growth, and open up vast discovery potential surrounding the evolution of the Universe's earliest black holes ..read more

Humanity may not be extraordinary but rather the natural evolutionary outcome for our planet and likely others, according to a new model for how intelligent life developed on Earth ..read more

A unique dataset of Type Ia Supernovae being released today could change how cosmologists measure the expansion history of the Universe ..read more

Scientists have just detected a neutrino that is thirty times more energetic than any previously detected anywhere in the world. This exceptional discovery opens up new perspectives for understanding extreme energy phenomena in the Universe and the origin of cosmic rays ..read more

Euclid, the European Space Agency's dark Universe detective, has made an astonishing discovery -- right in our cosmic backyard ..read more

A team of international researchers has developed an innovative approach to uncover the secrets of dark matter in the cosmos. They are searching for dark matter using atomic clocks and cavity-stabilized lasers ..read more

Astronomers have characterized the largest-ever early-Universe radio jet. Historically, such large radio jets have remained elusive in the distant Universe. With these observations, astronomers have valuable new insights into when the first jets formed in the Universe and how they impacted the evolution of galaxies ..read more
