The mantis whirls around, spreads its black-patterned wings and puts its arms behind its head in a pose reminiscent of Edvard Munch’s “The Scream,” showing off shocking red undersides.
Astronomers have known for two decades that the expansion of the universe is accelerating, but the physics of this expansion remains a mystery. Now, a team of researchers at the University of Hawaii at Manoa has made a novel prediction — the dark energy responsible for this accelerating growth comes from a vast sea of compact objects spread throughout the voids between galaxies. This conclusion is part of a new study published in The Astrophysical Journal.
Astronomers have found that the key to understanding galaxies with “extreme” sizes, either small or large, may lie in their surroundings.
Pierogies are pretty easy to make at home because dumpling dough is softer and more pliable than pasta dough and therefore easier to roll out. There’s no yeast or rising time — just a brief resting period. Another plus: Making your own dumplings puts you in the driver’s seat with the fillings.
