Webb Unveils Previously Unseen Formations within the Renowned Supernova

Astronomy, Astrophysics, Planetary Science, Science / Ngoma Manuel

The James Webb Space Telescope from NASA has initiated its examination of the famous supernova, SN 1987A, situated 168,000 light-years distant in the Large Magellanic Cloud. This supernova has been under extensive scrutiny for nearly four decades, spanning from gamma rays to radio waves, since its detection in February 1987. Fresh observations using Webb’s NIRCam […]

NASA’s TESS Mission has Detected a Small Exoplanet Resembling Neptune in Size

Astronomy, Planetary Science, Science / Marcílio Santos

By employing NASA’s Transiting Exoplanet Survey Satellite (TESS), a group of astronomers from around the world has detected a fresh, substantial, and compact exoplanet. This recently discovered extraterrestrial planet, named TOI-332 b, ranks among the most densely-packed Neptune-sized planets ever observed. The discovery is detailed in a paper released on August 23 and available on

Recently identified Sun “Nanoflares” May Serve as the Origin of Solar Wind

Astronomy, Planetary Science, Science / Jorge Paka

While outer space lacks traditional air, it experiences a unique form of wind known as solar wind, composed of charged particles emitted by the Sun. The precise process driving this phenomenon remains unclear, but the Solar Orbiter spacecraft from the European Space Agency (ESA) has recently detected hitherto undiscovered “small-scale” eruptions on the Sun’s surface

Discovery of an Active Galactic Nucleus (AGN) in the Sombrero Galaxy

Astronomy, Galactic Astronomy, Science / Ngoma Manuel

A recent analysis of images captured by the Hubble Space Telescope (HST) has unveiled an intriguing find within the Sombrero Galaxy. Conducted by Elio Quiroga Rodriguez from the Mid Atlantic University in Spain, this discovery sheds light on a previously unnoticed galaxy that harbors an active galactic nucleus (AGN). The findings were detailed in a

The August Night Sky is Set to be Illuminated by the Dazzling Perseid Meteor Shower

Astronomy, Astrophysics, Science / Jorge Paka

The Perseid meteor shower is set to peak on the night of 12-13 August this year, promising an exciting spectacle for skywatchers. This meteor shower is most visible from the northern hemisphere, and under perfect conditions with clear skies, observers might be treated to an impressive display of up to 50 meteors per hour. Meteors

Recent Image Unveils the Mysteries Surrounding the Formation of Planets

Astronomy, Planetary Science, Science / Jorge Paka

Today, the European Southern Observatory has shared a stunning new image providing valuable insights into the potential formation process of Jupiter-sized planets. By employing the advanced capabilities of ESO’s Very Large Telescope (VLT) and the Atacama Large Millimeter/submillimeter Array (ALMA), scientists have identified sizable dusty clusters near a young star. These clusters hold the possibility

Using Gravitational Waves to Hunt for Dark Matter

Astronomy, Astrophysics, Physics, Quantum Physics, Science / Marcílio Santos

A global team of cosmologists has discovered through computer simulations that observing gravitational waves from merging black holes can reveal the real nature of dark matter. Dr. Alex Jenkins of University College London will co-author their discovery today at the 2023 National Astronomy Meeting. The team studied the production of gravitational wave signals in simulated

The Oldest Cosmic Web Strands Are Identified by Webb

Astronomy, Galactic Astronomy, Science / Ngoma Manuel

Instead of being randomly dispersed throughout the universe, galaxies cluster into intricate filamentary structures with enormous gaps in between. An exciting discovery of a thread-like structure of 10 galaxies that existed barely 830 million years after the Big Bang was made by astronomers using the James Webb Space Telescope. This 3 million light-year-long filament is

How a Scientist Weighed Black Holes Invisible to The Naked Eye

Astronomy, Astrophysics, Science / Salomão André

Joseph Simon, a postdoctoral researcher at the Department of Astrophysical and Planetary Sciences at the University of Colorado, Boulder, employed computer simulations to make predictions about the masses of the largest supermassive black holes existing in the universe. In a press statement, Simon highlighted the substantial mass of the black hole situated at the center
