Pulsars and magnetars are two distinct types of neutron stars that play significant roles in astrophysics. Pulsars are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation, primarily observed in radio wavelengths, while magnetars possess extraordinarily strong magnetic fields, leading to intense bursts of X-rays and gamma rays. The article explores their defining…

Exploring Dark Matter: What We Know and What We Don’t
Dark matter is a form of matter that does not emit, absorb, or reflect light, making it invisible and detectable only through its gravitational effects. It constitutes approximately 27% of the universe’s total mass-energy content and was first identified through observations of galaxy rotation curves in the 1930s. Key evidence supporting its existence includes gravitational…
Cosmic Microwave Background Radiation: A Snapshot of the Early Universe
Cosmic Microwave Background Radiation (CMBR) is the remnant radiation from the Big Bang, providing crucial evidence for the universe’s early conditions approximately 380,000 years after its formation. Discovered in 1965 by Arno Penzias and Robert Wilson, CMBR has a uniform temperature of about 2.7 Kelvin and exhibits slight anisotropies that reveal density variations essential for…
