400 Earth-mass rogue planets in the Milky Way Galaxy? NASA explains

[ad_1] NASA reveals that the Milky Way Galaxy may contain over 400 Earth-mass rogue planets. These rogue planets drift in space and they do not orbit any star at all, which makes them special. It is speculated that these planets are hidden in the Milky Way Galaxy and NASA's Nancy Grace Roman Space Telescope could spot over 400 of these rogue planets. According to NASA's report, the unknown planets were from outside the galaxy, but drifted into it with some unknown mechanism. “We estimate that our galaxy is home to 20 times more rogue planets than stars – trillions of worlds wandering alone,” said David Bennett, a senior research scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. About the rogue planet and upcoming missionSo far we know that planets outside the sol...

NASA Astronomy Picture of the Day 1 June 2023: Supernova Remnant Cassiopeia A

[ad_1] Today's NASA Astronomy Picture of the Day is a snapshot of Cassiopeia A, a supernova remnant located about 11000 light-years from Earth towards the constellation of Cassiopeia. When a star explodes, the subsequent explosion which takes place, known as a Supernova, is the largest explosion to occur in space. According to NASA, a supernova happens when there is a change in the core, or center, of a star. A change can occur in two different ways, with both resulting in a supernova.Although a supernova occurs for only a short span of time, it can tell scientists a lot about the universe. By studying supernovas, scientists have also shed light on the fact that we're living in an ever-expanding universe. Tech used to capture the imageThe picture was captured by the Chandra X-ray Observ...

Milky Way Galaxy and signs of life and water: Check out what this study found

[ad_1] A many as 1/3rd of the planets revolving around the most common stars across the Milky Way Galaxy may have liquid water and can possibly harbour life, according to a study based on latest telescope data. Most of the common stars in our galaxy are smaller and comparatively cooler. They are sporting just half the mass of the Sun at most. Billions of planets revolve around these common dwarf stars.Two-thirds of the planets around these ubiquitous small stars could be roasted by tidal extremes, sterilising them, shows the analysis which was published in the journal Proceedings of the National Academy of Sciences. Sheila Sagear, a doctoral student at the University of Florida (UF) in the US, said "I think this result is really important for the next decade of exoplanet research, becau...

NASA Astronomy Picture of the Day 29 May 2023: Milky Way Galaxy and the Bioluminescent Sea

[ad_1] Our solar system, with the Sun at the center and 8 other planets besides Earth, reside in an obscure part of a galaxy known as the Milky Way Galaxy. It is a barred spiral galaxy that spans about 100,000 light-years across and was formed approximately 14 billion years ago. According to NASA, the Milky Way Galaxy has over 100 billion stars and all of them orbit a supermassive black hole at the galaxy's center, which is estimated to be four million times as massive as our Sun.NASA's Astronomy Picture of the Day is a breathtaking snapshot of the Milky Way Galaxy captured over the bioluminescence of the sea in the Maldives. What is the turquoise glow in the water? It occurs due to single-celled Planktons, known as Noctiluca scintillans, which illuminate when stimulated by the sea wave...

ET calling from Mars? Just a test, but you can help decode the signal from robotic orbiter

[ad_1] After extensive efforts to detect extraterrestrial intelligence, a message from outer space was picked up by three prominent Earth-based radio astronomy observatories today. The signal originated in the vicinity of Mars, and its contents remain hidden at present. However, contrary to initial excitement, the message is not of extraterrestrial origin. It was deliberately transmitted as part of a simulation to mimic an actual communication from aliens. This exercise serves as a dress rehearsal, enabling us to gauge our preparedness and response if we were to encounter a genuine extraterrestrial message. This was organised by the astronomers at the SETI Institute in Mountain View, California.SETI is devoted to searching for signs of extraterrestrial intelligence and it aims to initia...

NASA Astronomy Picture of the Day 10 May 2023: Milky Way Galaxy visible in Egyptian skies

[ad_1] The Milky Way Galaxy is our home galaxy. Our solar system, with the Sun at the centre and 8 other planets, reside in an obscure part of the Galaxy. It is a barred spiral galaxy which spans about 100,000 light-years across and was formed approximately 14 billion years ago. The Milky Way Galaxy has over 100 billion stars and all of them orbit a supermassive black hole at the galaxy's center, which is estimated to be four million times as massive as our Sun, according to NASA.Today's NASA Astronomy Picture of the Day is a snapshot of the Milky Way Galaxy shot in the Egyptian Desert. How does the Milky Way Galaxy get its name? Before we had telescopes, people could not see many of the stars very clearly. They blurred together in a white streak across the sky.

2 galaxies TWINNING! NASA Hubble Space Telescope snaps unique moment in time

[ad_1] Space sometimes gives us unique and interesting events in time to watch with the help of telescopes like the iconic Hubble Space Telescope, or the newly launched James Webb Space Telescope, and more. NASA on its Instagram account has shared an amazing glimpse clicked by the Hubble Space Telescope. The Hubble Space Telescope has recently celebrated its 33rd launch anniversary, and after a week of the same the telescope has captured a mesmerizing image of neighbouring galaxies.Sharing the image on Instagram, the space agency captioned it by writing, "Look at those two buddies. Just hanging out. Doing their thing." Giving further details about the image, NASA added, "This starry pair offers a glimpse of what our Milky Way galaxy would look like to an outside observer. The edge-on ga...

Threat to life! NASA scientists identify new stellar danger to planets

[ad_1] Astronomers using data from NASA's Chandra X-ray Observatory and other telescopes have identified a new threat to life on planets like Earth: a period during which intense X-rays from exploded stars can affect planets over 100 light-years away.The finding, published recently in The Astrophysical Journal, has implication for the study of planets outside the solar system and their habitability. This threat comes from a supernova's blast wave striking dense gas surrounding the exploded star. When this impact occurs it can produce a large dose of X-rays that reaches an Earth-like planet months to years after the explosion and may last for decades, the researchers said. Such intense exposure may trigger an extinction event on the planet, they said.The study is based on X-ray observati...

NASA Astronomy Picture of the Day 12 April 2023: Star cloud in the Andromeda Galaxy

[ad_1] The Andromeda Galaxy is home to several interesting objects, including globular clusters, planetary nebulae, and supernovae. It is one of the most distant, yet easily visible objects to the eye. Since Andromeda is one of the most easily seen celestial objects, it is unclear who discovered it. However, the first written observation of the Andromeda Galaxy can be found in Persian astronomer Abd al-rahman al-Sufi's The Book of Fixed Stars which dates back to the year 964.Today's NASA Astronomy Picture of the Day is the star cloud NGC 206 in the Andromeda Galaxy. It is the brightest star cloud in the galaxy as seen from Earth. Also known as Messier 31, it is a spiral galaxy located approximately 2.5 million light-years away from Earth in the constellation Andromeda. According to NASA...

NASA Hubble Space Telescope finds a MONSTER black hole weighing as much as 20 million Suns

[ad_1] There are several giant objects floating in space. From massive planets to enormous asteroids and more. But they all pale in comparison to the latest NASA find. The NASA Hubble Space Telescope has detected a 'monster' runaway black hole. Amazingly, NASA has also stated that if the black hole was in our solar system, it could travel from Earth to the Moon in 14 minutes. The supermassive black hole also weighs as much as 20 million Suns. The strange part about this discovery is the unusual movement pattern of the black hole and the fact that it is forcing star formations instead of eating them."There's an invisible monster on the loose, barreling through intergalactic space so fast that if it were in our solar system, it could travel from Earth to the Moon in 14 minutes.
