Astronomers May Have Spotted Another Neutron Star Merger



In 2017, gravitational waves and light were observed coming from the merger of a pair of neutron stars. The discovery proved that gravitational wave sources could also be viewed at visible, X-ray, and even gamma-ray wavelengths, but has remained the only such event observed to date. Now, researchers have identified a “cosmic look-alike” — an event they believe came from the same type of system as the one that produced the gravitational waves.

Seeing Double

Such a discovery would double the number of known events of this type. “It’s a big step to go from one detected object to two,” said Eleonora Troja of NASA’s Goddard Space Flight Center, and lead author of the study published October 16 in Nature Communications, in a press release. The paper focuses on a gamma-ray burst, called GRB 150101B, seen by NASA’s Neil Gehrels Swift Observatory in 2015. Troja’s team followed up using NASA’s Chandra X-ray Observatory, Fermi Gamma-ray Space Telescope, Hubble Space Telescope, and the Discovery Channel Telescope to determine that GRB 150101B appears similar to the 2017 gravitational wave event GW170817, which was produced by a kilonova that occurred when two inspiralling neutron stars collided. Shortly after that event’s gravitational waves reached Earth, astronomers also spotted a gamma-ray burst and light at several wavelengths associated with the merger, proving that neutron star mergers are capable of producing all these signals.
During a neutron star merger, astronomers believe a narrow jet of high-energy particles is created, which is responsible for the short burst of gamma rays spotted from Earth. In the case of both GW170817 and GRB 150101B, that jet was likely viewed off-axis, meaning it was not directly pointed toward our planet, because the bursts were fainter and shorter lived than expected. Both events also generated bright blue light at visible wavelengths (the kilonova) and lasting X-ray emission. The two even came from host galaxies that look similar: old elliptical galaxies with no newly forming stars.

“It’s OK not to be OK”

“It’s OK not to be OK”. Abilities have different contours, and have shaped the destiny of mankind beyond imagination. 

Dyslexia is one such ability which deprives a child of a ‘Reading Brain’. Though gifted with an ability to understand complex ideas, the manner in which the dyslexics grasp and comprehend information makes them unique and differential. An educator dealing with such creative individuals has to think out of the box making the learning environment more inclusive and encouraging at all times. Bringing such learners from the margin to the mainstream shall be based on the principle that “Every student can learn , may be just not on the same day or the same way”.

The book- “ Educating Exceptional Children- An Introduction to special Education”, by      Dr. S.K. Mangal, not only provides an insightful and vivid discussion on various aspects of special learners both cognitively impaired and learning impaired but it also presents practical experiences of special educators in the form of case studies.

The book lays emphasis on harnessing the innate potential of each learner by the educator and provides a plethora of ideas and techniques to do wonders with such learners. The book follows the Ethos: “All people see the disabilities, but a special educator unleashes the possibilities.”
