What is Uranus?

Uranus, the seventh planet from the Sun, is a fascinating celestial body that has captured the imagination of astronomers and space enthusiasts alike. Discovered by German-born British astronomer Sir William Herschel on March 13, 1781, Uranus is unique for various reasons, including its axial tilt, rotational characteristics, and its distinctive blue-green hue. One of the … Read more

New data science approach solves astronomical image matching problem

For those familiar with astronomical imaging, stacking multiple images to enhance signal strength is a common technique. However, in research projects requiring data spanning longer time frames from different locations and conditions, matching observations across survey runs poses a challenge. A team from the John Hopkins Institute introduces a novel approach, “mixed integer quadratically constrained … Read more

Webb telescope reveals intricate details of herbig-haro object 797

The latest Picture of the Month captured by the NASA/ESA/CSA James Webb Space Telescope unveils intricate details of Herbig Haro object 797 (HH 797). These luminous regions surround newborn stars, known as protostars, forming when stellar winds or jets of gas collide with nearby gas and dust at high speeds, creating shockwaves. Dominating the lower … Read more

New model unravels the mystery of gamma-ray bursts

Utilizing cutting-edge computer simulations alongside theoretical calculations, astronomers are gaining deeper insights into the origins of gamma-ray bursts (GRBs), some of the universe’s most energetic phenomena. The newly proposed unified model affirms that certain prolonged GRBs result from cosmic mergers, giving rise to an infant black hole enveloped by a substantial disk of birth material. … Read more

New catalog of gamma-ray pulsars marks a milestone in pulsar research

The U.S. Naval Research Laboratory (NRL) and the international Fermi Large Area Telescope Collaboration have unveiled a groundbreaking discovery – almost 300 gamma-ray pulsars showcased in their Third Catalog of Gamma Ray Pulsars. This achievement marks a significant milestone, emerging 15 years after Fermi’s launch in 2008 when the count of known gamma-ray pulsars was … Read more

Planets in pristine solar systems also have slightly slanted orbits

The mystery of why planets in Earth’s solar system have slightly tilted orbits may not be so perplexing after all, according to a recent Yale-led study. In contrast to the common assumption that planets with tilted orbits result from cosmic disturbances, the research suggests that even in “pristine” solar systems—where planetary orbits have remained relatively … Read more

Cosmic orchestra: Six planets found dancing in harmony

In a nearby star system, scientists have unearthed an extraordinary phenomenon: a rhythmic orbital dance involving six planets gracefully encircling their central star. This celestial ballet unfolds with such precision that it can be translated into musical harmony, representing a rare instance of gravitational synchronicity. The unique gravitational lockstep observed in this system provides an … Read more

Solar cycle 25 peak likely to occur in early 2024

Researchers at the Center of Excellence in Space Sciences India, based at IISER Kolkata, have unearthed a novel connection between the sun’s magnetic field and its sunspot cycle, offering potential insights into predicting the peak of solar activity. Their findings, detailed in the Monthly Notices of the Royal Astronomical Society: Letters, suggest that the climax … Read more
