Ordinary matter, also called baryonic matter, consists of protons, neutrons, and electrons. This is the material that emits or absorbs radiation, allowing telescopes to observe stars, nebulae, and galaxies. From the largest galaxy cluster to the smallest grain of dust, everything visible belongs to this category. Yet despite its familiarity, this matter represents only a sliver of the cosmos. It …

Astronomers have discovered an incredibly rare system in which at least five galaxies from the early universe are merging — just 800 million years after the Big Bang. The remarkable discovery was made using data from the James Webb Space Telescope (JWST) and the Hubble Space Telescope. Galaxy mergers play a key role in galaxy formation in the early universe. …

One of the strongest indicators of this limit is the cosmic microwave background radiation, faint afterglow from the Big Bang. It was released when the Universe was just 3,80,000 years old, before which matter and energy were too tightly coupled for light to travel freely. Today it appears across the entire sky at a temperature of 2.7 degrees above absolute …

The universe feels simple at first glance: stars, gas, dust, and the gravity that binds it all. Then you look more closely and realize that nothing could be farther from the truth. For decades, the standard picture has said that most of what is out there is not what we can see. It is a mix of ordinary matter and …

Deep in the first moments of the Big Bang, the entire cosmos shook and rumbled. Those quakes still reverberate to the present day. It will take the most sensitive instruments ever imagined to reveal those ripples, but if they are discovered, they will change our understanding of the entire universe. In 1916, Albert Einstein discovered that his theory of general …

MIT Professor Emeritus Rainer Weiss ’55, PhD ’62, a renowned experimental physicist and Nobel laureate whose groundbreaking work confirmed a longstanding prediction about the nature of the universe, passed away on Aug. 25. He was 92. Weiss conceived of the Laser Interferometer Gravitational-Wave Observatory (LIGO) for detecting ripples in space-time known as gravitational waves, and was later a leader of …

IN A NUTSHELL 🔭 Researchers discovered a significant pattern in the rotational direction of ancient galaxies using the James Webb Space Telescope. 🌀 Approximately 60% of these galaxies rotate clockwise, challenging the previous belief of random galactic rotations. 🌌 A bold hypothesis suggests that our universe might be trapped within a massive black hole. 🔍 Alternative explanations consider observational bias, …

A monster galaxy from the early universe shows that the cosmos was rich with oxygen when it was only less than 3% of its present age, astronomers have found. The discovery raises questions about how early life could have first appeared in the universe. This isn’t the first time astronomers have looked at that enigmatic galaxy, named JADES-GS-z11-0. It was …
