The Hudson River, recently seen in the news, is located in which of the following countries?
Correct
Answer: b
Explanation:
New York and New Jersey recently sued the Trump administration for freezing $16 billion in federal funding for a new rail tunnel under the Hudson River between the two States.
About Hudson River
It is a river in New York State, United States.
It flows almost entirely within New York State, the exception being its final segment, where it forms the boundary between New York and New Jersey for 34 km.
It was named after British explorer Henry Hudson, who sailed up the river in 1609.
It originates in several small postglacial lakes in the Adirondack Mountains near Mount Marcy (1,629 metres), the highest point in New York, and flows about 507 km through the eastern part of the state.
Lake Tear of the Clouds is regarded as the source of its main headstream, the Opalescent River.
The water from the Hudson River flows into the Upper New York Bay that is situated between New York City and New Jersey.
At the New York Harbor, the Hudson River drains into the Atlantic Ocean.
Due to the glaciation and the rising sea levels, the lower portion of the river is a tidal estuary that occupies the Hudson fjord.
Together with the Mohawk River, its major tributary, it forms one of the US’s most important waterways.

Consider the following statements regarding the SPHEREx Mission, recently seen in the news:
It is a NASA Astrophysics mission.
It will produce a three-dimensional map of the universe.
Which of the statements given above is/are correct?
Correct
Answer: c
Explanation:
NASA’s SPHEREx mission turned its infrared gaze on interstellar comet 3I/ATLAS recently, adding to the deep pool of information the agency has gathered on what is only the third such object to be discovered passing through our solar system.
About SPHEREx Mission:
It is a NASA Astrophysics mission launched on March 11, 2025.
The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) telescope is a megaphone-shaped telescope.
It will provide an all-sky spectral survey.
It will survey the sky in optical as well as near-infrared light, which, though not visible to the human eye, serves as a powerful tool for answering cosmic questions.
Over a two-year planned mission, the SPHEREx Observatory will collect data on more than 450 million galaxies along with more than 100 million stars in the Milky Way in order to explore the origins of the universe.
With this capability, SPHEREx will produce a three-dimensional map of the universe unlike any other.
Scientists will use this map to answer big questions about the early universe, the history of galaxies, and the prevalence of life-sustaining molecules in planet-forming regions of space.
It also will identify targets for more detailed study by future missions, such as NASA’s James Webb Space Telescope and Wide Field Infrared Survey Telescope.
